REAPER Spectral Repair in 7.75: Clicks, Dropouts, Empty Mixer Slots

Does REAPER Have Spectral Repair for Clicks and Dropouts?

Yes—for short, local defects. Spectral repair lives in the sample-edit toolset introduced earlier in the 7.7x line. Version 7.75 added actions that replace a time selection with content extrapolated from audio before and after it. Cockos frames the use case as fixing pops, clicks, and dropouts.^[3][2]

That differs from older REAPER spectral edits (frequency-band gates/compressors on a spectrogram). Spectral repair is reconstructive: mark the bad region, run the action, and REAPER synthesizes replacement samples from neighborhood context. Bias, scale, balance, DC correction, and fades let you weight preceding vs following material and smooth edges.^[3]

If the daily pain is a cracked snare, a digital glitch in a vocal take, or a one-sample dropout in a loop—not broadband denoise, music rebalance, or dialogue isolate—stock REAPER 7.75+ is a serious first stop. Suites such as iZotope RX still win when you need module depth and batch post workflows.

How REAPER Spectral Repair Works at Sample Level

Sample edits are per-take envelopes over individual sample values—non-destructive while the take remains unglued. You zoom in, edit values, or run reconstructive actions over a time selection. Spectral repair analyzes audio around the selection and writes a replacement instead of zeroing samples or drawing a straight line.^[3]

Point releases tightened the workflow after the initial ship. 7.76 added delete-all sample-edit actions, razor-edit targeting for first-selected-item variants, mono-downmix handling, and a smaller analysis window for very short repairs. It warns when a sample-edit action exceeds roughly 16k samples, while still allowing much larger edits at project-size cost.^[3] Treat that as design intent: spectral repair is for surgical lengths, not whole-bar reconstructions.

• Best targets Single clicks, digital ticks, short dropouts, bad zero-crossings, and isolated glitches inside otherwise clean audio or sample loops.
• Dialog controls that matter Bias (favor pre- or post-selection material), scale/balance, DC offset correction, and fades. Flip bias when a glitch sits next to a hard transient.
• Session safety Edits live on the take. Duplicate the item before aggressive surgery. Enable the 7.75 preference that auto-zooms to the time selection when running sample-edit actions so you never repair blind.
• What it is not Not global de-noise, Music Rebalance, Dialogue Isolate, or a batch post pipeline. Use a dedicated repair suite for those jobs.

Workflow: Fix Clicks and Dropouts on Samples

Use this sequence on one-shots, loop slices, and short vocal glitches. Work on a copy when the sample is shared across tracks or is a catalog asset you may re-export later.

1. Locate the defect at sample zoom
   Solo the item, zoom until samples are visible, and set a tight time selection covering only the bad region plus a few clean samples on each side.
2. Enable sample edits if needed
   Activate sample editing for the take when required. Incompatible compressed sources may need conversion to PCM first—heed any media-compatibility dialogs.
3. Run spectral repair on the time selection
   Trigger spectral repair (or the first-selected-item-in-time-selection variant). Start with moderate bias toward the cleaner neighbor, light fades, and DC correction if the glitch introduced offset.
4. A/B and refine
   Play at normal and zoomed views. If you hear chirps or smeared transients, shorten the selection, flip bias, or fall back to set-samples-to-zero/line for pure digital spikes.
5. Commit, glue only when shipping
   Leave sample edits live while the mix is open. Glue or render a replacement file only when handing off stems or freezing a finished loop asset.

Power-user shortcuts around sample edits

Bind spectral repair, delete-sample-edits-in-selection, and set-samples-to-zero/line to neighboring keys. Cockos kept refining edges in 7.76–7.78 rather than shipping once and freezing the toolset—re-check the Actions list after updates for new sample-edit variants.^[1][3]

Empty Mixer Slots, Multi-Track Slot Bypass, and Sends

The other 7.75 headline is long-requested empty FX slots in the TCP and MCP. Empty slots are off by default: enable them from the Options menu (Allow empty slots in track control panel and mixer) or from the mixer context menu. Then leave intentional gaps so every track’s compressor can live in slot 2 and EQ in slot 3—even when a track skips a stage.^[2][3]

Aligned slots make actions that toggle FX bypass for slots 1–10 on selected tracks into mix-wide macros: select drums, bypass slot 4, compare, re-enable. Version 7.77 added modifier clicks (Alt+Shift / Alt+Ctrl+Shift on FX or send slots) that toggle bypass/mute for a slot across selected or all visible tracks—the multi-track workflow empty slots were meant to unlock.^[3]

Sends gained empty-slot discipline plus destination-colored level indicators, so complex cue and parallel graphs stay legible. Later 7.7x builds made the tint configurable in the theme tweaker.^[3][1] For beatmakers and small commercial rooms this reduces “which plugin am I bypassing?” errors under deadline.

REAPER Spectral Repair vs iZotope RX

Community coverage of 7.75 framed the release as mixer slots plus sample-edit spectral repair—not “RX is dead.” That framing is correct. REAPER closes a budget gap on spot reconstruction; RX remains a specialized post environment with deeper modules and batch dialogue tools.^[2]

REAPER’s discounted personal/educational/small-business license is $60 when yearly gross revenue does not exceed USD $20,000 (or personal/non-profit use). Commercial use above that threshold is $225. Evaluation is full-featured for 60 days with no registration required.^[4][1] For many home studios already in REAPER, 7.75 means fewer bounces to RX for every click. When weekly dialogue salvage or music rebalance appears, buy the dedicated suite—do not pretend stock repair covers every module.

When Stock Tools Are Enough (and When Premium Repair Wins)

• Stay in REAPER when… Defects are short, isolated, and the musical context around them is clean—loop libraries, one-shots, drum ticks, single vocal glitches.
• Open RX (or similar) when… You need repeatable modules on long dialogue, heavy broadband noise, multi-take mouth-noise cleanup, or ML isolation.
• Combine both when… Do most click/dropout salvage in REAPER during edit, then send only stubborn regions to a repair suite.
• Upgrade sample libraries when… You repair the same weak one-shots every session. Cleaner sources beat clever reconstruction; reach for better packs when character is still missing after cleanup.

Frequent free updates matter: spectral repair and slot tools arrived as normal point releases, then tightened in 7.76/7.77 (and further polish through 7.78) without a new paid tier.^[3] Run current 7.x, re-test key actions after updates, and keep a small custom-action set for repair plus slot A/B.

Power-User 7.75 Checklist Beyond Repair

Beyond the headlines, 7.75 also improved navigator accuracy with envelope lanes and spacers, MIDI Learn display of the last received value, media explorer column menus, and LTC detection for post-oriented sessions.^[2][3]

1. Turn on empty FX and send slots in a template
   Decide house chain order once. Save track templates with empty placeholders so new sessions inherit aligned slots.
2. Bind slot bypass 1–4 and spectral repair
   Four slot toggles plus one repair action cover most mix A/B and click-clean passes without opening the Actions list mid-session.
3. Color destination buses before building sends
   With send meters tinted by destination color, wrong routing shows up as wrong-colored meters.
4. Enable auto-zoom for sample-edit actions
   The 7.75 preference that zooms to the time selection prevents accidental long-range repairs.
5. Keep external repair tools for the long tail
   Personal rule: short sample-level defects → REAPER spectral repair; long or broadband issues → external denoise/RX-class tools.
