How to comp vocal takes in REAPER (build one great take from many)
Published July 30, 2026 · Updated July 30, 2026
Comping means building one strong vocal by picking the best moments from several recorded takes. In current REAPER (version 7.78), the quickest way is fixed item lanes with swipe comping: set the vocal track to Fixed Item Lanes, record a few passes so each one stacks into its own lane, arm a comp lane, then click and drag across the lanes below to keep the best bits. The older takes in lanes method still works too. Everything here uses REAPER’s stock features, so there is nothing to buy. Comping decides which take plays where. It does not fix a take that was never good.
If you sing a part three or four times, no single take is usually perfect. One has the best first line, another nails the chorus, a third has the cleanest ending. Comping (short for compositing) is how you stitch those best pieces into one continuous vocal. It is one of the biggest jumps in quality you can make without any new gear, and REAPER gives you two solid ways to do it.
This guide covers both: the modern fixed-item-lanes and swipe-comping workflow that REAPER 7 added, and the classic takes-in-lanes method that has been in REAPER for years. Pick whichever feels clearer. The end result is the same, a single clean vocal you can then mix.
Record a few usable takes first
Comping only works if you give it good raw material. Before you comp, record the part several times all the way through, keeping the mic position, level, and distance the same on every pass so the takes blend cleanly later. Three to five full passes is a sensible starting point for a verse or chorus. If you are new to setting up a clean recording session, it helps to set up a vocal template in REAPER so every take starts from the same place.
If one take is much louder, closer, or brighter than the others, the joins between them will jump out. Matching your position and gain across takes is what makes a comp sound like one performance instead of several glued together.
Method 1: Fixed item lanes and swipe comping (REAPER 7)
This is the workflow REAPER introduced in version 7. It keeps each take in its own lane inside a single track and lets you drag across the lanes to build the comp.
Turn the track into lanes
Right-click the vocal track and choose Fixed Item Lanes. The track can hold up to 128 lanes, which is far more than any vocal needs.
Record your passes
Record the part, then record it again over the same spot. Each new pass drops into its own lane, so after four passes you have four lanes stacked in the one track.
Audition the lanes
Use the small buttons on the left of each lane to isolate and listen to one lane at a time, so you know which passes are worth keeping.
Arm a comp lane
Right-click one of those lane buttons and choose Comping › Comp into new empty lane. REAPER creates a comp lane (labelled C1) with a highlighted background, which means swipe comping is now active.
Swipe the best parts
Click and drag across the lanes below to grab the section you like from each one. Each swipe copies that region up into the comp lane. Work left to right through the part, choosing the best version of every phrase.
Unarm when done
Double-click the comp lane to unarm it. The highlight disappears, which tells you the comp is safe to edit further without accidentally swiping in new pieces.
If you recorded before switching to lanes and your passes are stored as takes on one item, you do not have to re-record. Open the Actions list (press ?) and run Track properties: Fixed item lanes (convert takes to lanes) to move them into lanes.
Method 2: The classic takes-in-lanes way
This method predates fixed item lanes and still works in current REAPER. It is handy if your passes are already recorded as takes on a single item, or if you simply prefer it.
Stack your takes on one item
Recording repeatedly over the same item stacks each pass as a new take. Loop recording is a common way to capture several takes into one item quickly.
Show all takes in lanes
Right-click the item and choose Take › Show all takes in lanes so every take is laid out one above another and you can see them all.
Split and choose per section
Split the item at each point where you want to change take, then click the take lane that has the best performance for that section to make it the active take there.
Audition with the T key
Press T on a selected item to cycle through its takes, which is a fast way to compare options for one section without leaving the arrange view.
Finish the comp cleanly
However you built it, the last step is to consolidate the pieces into one continuous item so the rest of your mixing is simple.
Glue it into one item
Select the comped sections and glue them (Ctrl+Shift+G on Windows, Cmd+Shift+G on Mac) to render them into a single item. From that point the vocal behaves like one recording.
Mind the edit joins
The place a comp goes wrong is the join between two pieces, where you can get a click or an audible jump. REAPER can crossfade automatically at edit points when auto-crossfade is enabled, and you can set the default crossfade length under Options › Preferences › Project › Media Item Defaults. If a join still clicks, nudge the edit to a quiet gap between words or a breath, where a short crossfade is invisible.
Cutting in the middle of a held note or a word almost always sounds wrong, because the two takes will not line up in pitch or timing. Aim your edits at consonants, breaths, and gaps. That is where takes join without you hearing the seam.
| You want to | Do this | Where |
|---|---|---|
| Stack takes in one track (REAPER 7) | Set track to Fixed Item Lanes, then record passes | Right-click track |
| Build the comp by dragging | Arm a comp lane, then swipe across the lanes | Comping › Comp into new empty lane |
| Comp older stacked takes | Show all takes in lanes, split, pick the active take | Right-click item › Take |
| Compare takes fast | Cycle takes on the selected item | Press T |
| Consolidate to one item | Glue the finished comp | Ctrl/Cmd+Shift+G |
What comping will not do
Comping is powerful, but it only chooses between what you actually recorded.
- It will not rescue a bad performance. If none of your takes has a good version of a line, comping cannot invent one. Record another pass instead.
- It will not fix pitch or timing inside a take. Comping picks whole regions. Correcting a flat note or a late entry is a separate job. See how to tune vocals in REAPER for free for the pitch side of that.
- It will not fix tone problems like muddiness or harshness. Those are EQ and dynamics decisions you make after the comp, not during it.
- It will not hide takes that do not match. If your mic moved between passes, no crossfade fully smooths the jump. That is a recording-consistency problem, not an editing one.
A good comp turns several rough passes into one confident, continuous vocal, which is usually the biggest single improvement a home recording gets. It sets up everything after it, but it is the start of the mix, not the whole mix.
If it still sounds off
Quick troubleshooting order when a comp is not sitting right:
- The joins click or jump. Move each edit to a breath or a gap between words and enable auto-crossfade so short fades smooth the transition.
- Takes do not blend. If one section is clearly louder or brighter, your takes were not recorded consistently. Match levels, or re-record the odd one.
- You cannot find a good version of a line. Stop comping and record one or two more passes of just that phrase, then comp those in.
- Timing drifts between takes. If you monitored with delay while recording, entries can land late and never line up. Fix the monitoring first. See how to fix recording latency in REAPER.
Comping builds one great vocal from several takes. In REAPER 7, set the track to Fixed Item Lanes, record a few passes, arm a comp lane, and swipe the best parts together. On any REAPER version you can show all takes in lanes, split, and choose the best take per section instead. Glue the result, keep your edits on breaths and consonants, and remember that comping picks between takes but does not fix pitch, tone, or a performance that was not there.
