Restore a vinyl transfer in separate, conservative stages: capture and protect the best playback first, diagnose overload and hum, remove the largest clicks, reduce dense low-level crackle, and spot-repair leftovers. Then decide whether remaining surface noise or pitch instability still distracts from the music. Compare the order of hum and click repair on a short copy when both are prominent.

Do not aim for digital silence. The right result keeps percussion attacks, brass edges, vocal consonants, room tone and the record's character while pushing damage behind the performance. Removed-signal monitoring and level-matched bypass checks matter more than a preset number.

This workflow uses the standalone [RX 12 Audio Editor in Standard or Advanced](https://docs.izotope.com/rx12/en/rx-overview.html?ref=izotoperx.net). Standard includes De-click, De-crackle, De-hum, Interpolate, Spectral Repair and Spectral De-noise. Deconstruct and Wow & Flutter require Advanced. Elements supplies six DAW plug-ins without the standalone editor, so it cannot perform this complete workflow.

## Start with the physical transfer, not a repair preset

Software cannot recover information the stylus never read. Inspect and clean the record and stylus with appropriate methods, confirm turntable setup, use the correct phono preamp path, and record a level that leaves headroom for unexpected pops.

Follow the cleaning instructions for your record, stylus and equipment. The IASA [microgroove-record transfer guidance](https://www.iasa-web.org/book/export/html/473?ref=izotoperx.net) covers cleaning, replay equipment and equalisation. Its historical scope matters: early LP equalisation was not uniform, and shellac 78s need their own carrier-appropriate methods. For an ordinary vinyl project, get the safest clean playback you can and keep that transfer unchanged.

Record enough lead-in and run-out groove to hear the noise floor, but do not assume those sections perfectly represent noise under music. Save the raw transfer as a separate file before opening repair modules. The [RX safe-saving workflow](https://izotoperx.net/izotope-rx-import-export-save/) separates the untouched source, editable RX Document and delivery render.

## Run capture QC before RX cleanup

Listen to the raw file from beginning to end. Inspect every track boundary and the loudest passages closely, and check left and right channels separately for dropouts, unexpected level imbalance and intermittent contact noise. Check the physical left/right connections if the channel assignment is uncertain. Confirm stable turntable speed and sufficient capture headroom for large pops.

Log the record identity, side, turntable, cartridge and stylus, phono preamp, converter, sample rate, bit depth and capture date. Those details make a later recapture comparable. IASA’s [technical preservation principles](https://www.iasa-web.org/ethical/222-technical-processing-and-preservation?ref=izotoperx.net) require documented transfers and place subjective cleanup on a copy of the unmodified archival transfer. The cleaned listening file is a separate deliverable.

If the raw transfer has a repeating channel fault, unstable connection or obvious mistracking, correct the playback problem and capture again. RX is the right tool for damage that belongs to the carrier or irreplaceable transfer, not a substitute for a cable, stylus or gain-stage fix that is still available.

## Map each vinyl defect to one job

| Defect to investigate               | Candidate and listening check                                              |
| ----------------------------------- | -------------------------------------------------------------------------- |
| Squared, overloaded peaks           | De-clip. Protect true drum and brass peaks.                                |
| Stable 50/60 Hz tone and harmonics  | De-hum. Protect bass fundamentals.                                         |
| Large isolated vertical pops        | De-click. Protect musical transients.                                      |
| Dense quiet ticks forming a texture | De-crackle. Protect timbre and high-frequency detail.                      |
| A few stubborn local events         | Interpolate or Spectral Repair. Protect timing and surrounding ambience.   |
| Steady hiss or groove noise         | Spectral De-noise or Deconstruct. Protect air, reverb and low-level decay. |
| Slow or fast pitch modulation       | Wow & Flutter. Protect intentional vibrato and expression.                 |

The current [iZotope cleanup guide](https://www.izotope.com/community/blog/how-to-clean-up-audio-and-remove-background-noise?ref=izotoperx.net) distinguishes De-click's isolated impulses from De-crackle's continuous stream of quieter clicks. That distinction drives the order.

## Ten steps to restore a vinyl transfer

1. **Prepare playback.** Inspect and clean the carrier and stylus appropriately, then confirm stable tracking and the correct signal path.
2. **Capture with headroom.** Record the complete side and preserve the untouched transfer separately.
3. **Diagnose the side.** Listen throughout and mark overload, hum, large pops, dense crackle, remaining noise and pitch drift.
4. **Repair diagnosed overload.** Fix a recapturable gain-stage fault first; otherwise compare De-clip on demonstrated clipping and check reconstructed peaks.
5. **Compare hum and click order.** If both are present, test their order on a short copy. Use De-hum only for diagnosed tonal interference and protect bass.
6. **Reduce large clicks.** Tune De-click on pops and musical transients. Use Listen during Preview to hear removed clicks, then turn Listen off and approve the repaired music before rendering.
7. **Reduce dense crackle.** Compare De-crackle after the largest clicks. Use Listen during Preview to check removed crackle, then turn Listen off and approve normal music before rendering.
8. **Spot-repair leftovers.** With Instant Process off, make precise selections and choose Interpolate or Spectral Repair for each exceptional event.
9. **Assess residual noise and pitch.** Compare denoise or Advanced Deconstruct only if needed. Run Advanced Wow & Flutter separately from Module Chain with Display disabled for correction.
10. **Approve and export.** Compare at matched loudness, export a separate listening copy, reopen it and listen throughout while verifying channels, boundaries, resolution and peaks.

## De-clip only when the transfer clipped

A loud pop can overload a stage of the playback or capture chain. Flat tops, asymmetric flattened peaks and a concentration of samples near a clipping level are useful evidence; listen for distortion and inspect the De-clip histogram too. A pointed drum transient is not proof of clipping, and the absence of a perfect flat top does not rule out analog overload.

If repeated overload can be fixed, correct the gain at the stage that is actually clipping and recapture. Lowering the converter input will not undo distortion already produced by a phono preamp. For an irreplaceable transfer, compare a local De-clip repair, setting its threshold just below the diagnosed clipping level. Check the reconstructed peaks and leave export headroom.

The [RX De-clip guide](https://izotoperx.net/fix-clipped-audio-rx-de-clip/) covers threshold diagnosis and quality checks without conflating surface clicks with overload.

## Treat electrical hum without thinning the bass

Grounding trouble and the analog playback chain can add a stable fundamental with harmonics. Inspect the spectrogram for horizontal lines and use De-hum only when that tonal pattern is present. Do not high-pass the entire transfer aggressively just because the turntable has some low-frequency energy.

For a clear mains tone with a few harmonics, compare Static mode. Dynamic mode targets more complex buzz and interference. The [RX 12 De-hum manual](https://docs.izotope.com/rx12/en/de-hum.html?ref=izotoperx.net) recommends hum repair before broadband denoising; it does not establish one mandatory position before De-click. Compare hum-first and click-first on the same short copy if the defects interfere with detection.

Keep bass notes in the test loop. In the RX 12 Editor, enable **Listen**, the ear icon beside Compare, then click **Preview** to hear removed hum. The De-hum manual still calls this Output Hum Only; the [current module-footer documentation](https://docs.izotope.com/rx12/en/common-module-controls.html?ref=izotoperx.net) explains Listen. Recognizable bass or sustained notes there are a reason to reduce or reconsider the repair. Turn Listen off and judge the repaired music before committing it. Non-tonal turntable rumble is a different diagnosis from a narrow mains fundamental.

The [RX De-hum tutorial](https://izotoperx.net/izotope-rx-de-hum/) separates a fixed fundamental, harmonics, buzz and non-tonal rumble.

## Run De-click on the obvious pops

Vinyl pops and scratches appear as brief impulses, often as bright vertical structures in the spectrogram. Start with representative passages: one obvious pop, percussion, vocal consonants, brass and quiet music. Raise Sensitivity until the damage is found, then enable Listen and click Preview to audition removed clicks.

If the removed signal contains snare attacks, piano hammers or consonants, the setting is too aggressive or the algorithm/selection is wrong. The removed signal should contain defects with as little recognizable music as possible.

The [RX 12 De-click manual](https://docs.izotope.com/rx12/en/de-click.html?ref=izotoperx.net) identifies **Multi-band Random Clicks** as a candidate for wider vinyl clicks and thumps while protecting periodic material such as brass. Compare it on your transfer rather than treating it as a guaranteed preset. The full [RX De-click tutorial](https://izotoperx.net/izotope-rx-de-click-tutorial/) explains the other algorithms and Click Widening. Older tutorials call the removed-signal option Clicks Only. In the current Editor, turn Listen off and compare the repaired music with Bypass before rendering the chosen settings.

## Run De-crackle after the biggest clicks

Crackle is made of many low-level clicks close together. De-crackle is more effective after De-click removes the worst events, because the second detector can focus on the dense residual texture.

The [RX 12 De-crackle controls](https://docs.izotope.com/rx12/en/de-crackle.html?ref=izotoperx.net) include Quality, Strength and Amplitude Skew. The manual retains the label Output Crackle Only for removed-signal monitoring, while its current Editor image shows the Listen ear button. High Quality is intended to preserve tonal qualities; Strength changes detection and repair intensity. Move Amplitude Skew left to focus on quieter crackle or right toward louder crackle.

Enable Listen and click Preview to check the removed crackle. Recognizable cymbals, string bow texture or vocal air mean useful signal is being classified as damage. Back down before the cleaned file becomes smooth but lifeless. The dedicated [RX De-crackle workflow](https://izotoperx.net/izotope-rx-remove-crackle/) covers this boundary in depth.

Turn Listen off and approve the normal-output preview before rendering the cleaned version. If real-time playback struggles, compare rendered candidates instead of judging glitches caused by an overloaded preview.

## Spot-repair clicks that survive

Do not raise a whole-side setting for two stubborn pops. Turn **Instant Process off** before inspecting a selection, so selecting does not immediately process it. Zoom in and test [Interpolate](https://docs.izotope.com/rx12/en/interpolate.html?ref=izotoperx.net) only when the entire selection, including padding, is below 4,000 samples. At 48 kHz that is less than about 83.3 ms; use the selection’s sample count, not its apparent screen width. Longer or frequency-limited damage calls for a different repair.

For a complete short dropout, include the broken edges and compare Spectral Repair Replace using useful surrounding audio. Attenuate can reduce an isolated unwanted event where music remains; it does not reconstruct a fully missing passage. For a tiny pop, compare a tight local selection in Attenuate, Replace or Interpolate as appropriate. The [RX dropout-repair guide](https://izotoperx.net/izotope-rx-repair-audio-dropout/) covers selection readouts and the missing-audio decision.

Spot work is slower, but it preserves the rest of the side. It also creates an honest stopping point: a few harmless residual ticks are preferable to globally softened transients.

## Reduce steady surface noise gently

After click and crackle repair, decide whether the remaining hiss or groove noise is still distracting. With [Spectral De-noise](https://docs.izotope.com/rx12/en/spectral-de-noise.html?ref=izotoperx.net), learn a profile from representative noise without music, then compare conservative reduction across quiet and loud passages. Keep reverb tails out of a manually learned noise sample.

Noise changes across a record side, and lead-in groove is not always identical to noise under modulation. A profile that looks clean can produce watery tones, chirps or shortened reverberation when pushed.

A fixed profile suits relatively constant noise. Adaptive mode updates its estimate from incoming audio and can be compared for changing noise; it needs more processing resources and still requires careful listening. If neither route separates the noise cleanly, keep more of the noise floor instead of forcing reduction.

Advanced also offers [Deconstruct](https://docs.izotope.com/rx12/en/deconstruct.html?ref=izotoperx.net), which separates tonal and noisy components by structure rather than level alone. Its manual describes residual vinyl noise after De-click and De-crackle as a useful case, including varying noise. Compare a modest reduction in Noisy Gain while retaining tonal material. Hum can be classified as tonal, so this is not a universal hum-removal substitute. Compare Deconstruct with Spectral De-noise rather than stacking both automatically.

## Correct wow and flutter only when pitch really moves

[Wow & Flutter in RX 12 Advanced](https://docs.izotope.com/rx12/en/wow---flutter.html?ref=izotoperx.net) addresses pitch variation caused by unstable playback speed. Slow Wow targets 0–0.5 Hz, Medium 0.5–2 Hz, Fast 2–8 Hz and Flutter 8–40 Hz. These are modulation rates, not the pitches of the musical notes.

**Display Wow and Display Flutter are diagnostic modes.** Rendering with either enabled writes the detected contour into the audio and applies no pitch correction. Inspect a disposable copy, undo the diagnostic render or return to the untouched copy, then disable Display before rendering an actual correction. Do not export the diagnostic result as repaired music.

Do not apply pitch correction because an old record sounds old. Center-hole eccentricity, warped vinyl or unstable playback can cause real modulation, but performance vibrato, chorus and tape effects are musical information.

Use lower Sensitivity when needed to protect intentional vibrato. Leave **Center Global Pitch** off unless you have a reason to retune the recording: off preserves the selection’s length and average pitch; on centers it on the specified reference, whose default is 440 Hz. A frequency-limited selection guides detection, but correction is not confined to that frequency band.

## Separate repeatable processing from manual repairs

A starting sequence is diagnosed overload repair, hum and large-click treatment in the order that works better, De-crackle, spot repairs, then remaining noise and pitch decisions. Skip absent problems. If pitch instability prevents useful analysis, compare addressing it earlier on a copy. Each order is a candidate to audition, not a rule for every record.

The [RX Module Chain workflow](https://izotoperx.net/izotope-rx-module-chain/) can repeat supported processing stages. **Wow & Flutter is unavailable in Module Chain, Batch Processor and Composite View**; run it separately. Keep event-specific selections and spot repairs outside a generic whole-side chain, and listen after each risky stage.

In iZotope’s [remastering example using a Glenn Miller 78 RPM transfer](https://www.izotope.com/community/blog/remastering?ref=izotoperx.net), the author aims to push damage behind the music and describes an iterative process. That older-record example supports realistic expectations, not an RX 12 preset or a cleaning method for every carrier.

## Delay loudness processing until restoration is stable

Leave limiting and heavy compression until repair decisions are stable: they change the relationship between musical peaks and defects. Simple peak normalization is different. It applies gain to reach a target peak; it does not by itself improve the music-to-noise ratio or repair a click. Saving final level decisions for later keeps comparisons easier and preserves headroom for reconstructed peaks.

Work at a sensible level with headroom, reducing gain if reconstructed peaks need it. Once the restoration is approved, make a separate mastering stage for EQ, final level, limiting if wanted, and delivery. This lets you change presentation without repeating the repair.

Label the untouched transfer, cleaned access copy and listening master separately. IASA’s [unmodified-transfer principle](https://www.iasa-web.org/tc03/8-unmodified-transfer-new-target-format?ref=izotoperx.net) excludes subjective denoising from the archival transfer. Even gentle cleanup belongs on a derivative copy. Never overwrite the preservation source with a cleaned or louder version.

## Keep a light restoration beside the stronger version

After the large defects are controlled, save a lightly restored checkpoint before chasing the last noise. Create a second candidate only when the remaining bed is genuinely distracting. This makes the cost of additional De-crackle, denoise or pitch correction audible instead of theoretical.

Compare on full-range monitors, headphones and an ordinary playback system. The stronger version may sound impressively quiet in isolation yet reveal softened cymbals, narrowed ambience or unstable harmonics when level-matched to the light pass. Conversely, a few harmless ticks in the light version can disappear inside the music.

Retain the untouched archival transfer independently of listening-copy approval. Keep the RX Document and both rendered candidates through review so an editor can compare or revise the work. A sample or listening copy may need fewer deliverables, but approval of a cleaned version is not a reason to discard its preservation source.

Export the agreed listening format, then reopen that rendered file and listen through the full side. Verify channel order, track boundaries, fades, duration and peaks; a session that sounds correct does not prove the exported file is correct. Keep the transfer’s resolution documented rather than imposing one delivery setting on every recipient.

## Compare the right passages

- A quiet intro or fade where surface noise is exposed.
- A dense chorus where false detections may hide.
- Percussion, piano, brass and plucked-string attacks.
- Sibilants, vocal consonants and breath.
- Long sustained notes that reveal wow, flutter and denoise artifacts.
- The side break, lead-in, run-out and any manual repair seam.

Match playback loudness when comparing. A slightly quieter processed file can seem smoother even when it lost detail. Keep one lightly restored candidate beside any more aggressive version.

## Final vinyl-restoration quality gate

- The raw transfer remains untouched and documented.
- Clipping and hum were verified before their modules were used.
- De-click removed obvious pops without taking musical attacks.
- De-crackle reduced the dense texture without dulling timbre.
- Exceptional events were spot-repaired rather than forcing global settings.
- Denoise preserved air, decay and stable ambience.
- Wow & Flutter corrected mechanical pitch movement, not performance.
- The exported side retains required channels, resolution and metadata.

## Frequently asked questions

### What is the best RX order for vinyl restoration?

Start with an untouched transfer and diagnose each defect. A useful candidate is overload repair if needed, hum and large clicks in an order tested on a copy, De-crackle, local repairs, then remaining noise or pitch correction. Skip modules for problems that are absent.

### Should De-click run before De-crackle?

Usually yes. iZotope documents De-crackle as more effective after De-click removes the worst offending clicks.

### How do I keep RX from removing drum hits?

Include percussion in the comparison. In the RX 12 Editor De-click or De-crackle module, enable Listen and click Preview to hear removed content. If recognizable attacks appear there, reduce detection strength or change the algorithm and selection. Turn Listen off and judge the repaired music before rendering.

### Should I remove all vinyl noise?

No. Reduce noise until it stops distracting, then stop before air, reverb, cymbals and low-level musical detail become dull or watery.

### When should I use Spectral De-noise on vinyl?

Compare it for distracting residual hiss or groove noise after impulse repair. Learn a fixed profile from representative noise without music, or compare Adaptive mode for changing noise. Stop if useful detail becomes watery or dull.

### Can RX fix wow and flutter on a record?

RX 12 Advanced includes Wow & Flutter for mechanical pitch variation. Protect intentional vibrato and leave Display off for correction; Display renders a diagnostic contour, not repaired audio.

### Is De-crackle in RX 12 Standard?

Yes. RX 12 Standard and Advanced include De-crackle. Deconstruct and Wow & Flutter require Advanced; Elements has no standalone Audio Editor.

### What should I do with one pop that De-click misses?

Keep the global pass conservative and repair that event locally with Interpolate or Spectral Repair after making a precise selection.
