How to record vocals over a mastered beat that is too loud in REAPER

This is one of the most common dead ends for anyone recording to a purchased instrumental. You drag the beat in, it sounds loud and finished, you record a verse, and then the whole thing turns crunchy. So you turn the vocal up. It gets worse. You add a compressor to the voice to make it cut through. Worse again. Nothing you do to the vocal helps, because the vocal is not the problem.

The problem is that there is no space left in the project. Here is why that happens, how to confirm it in ten seconds, and what to set before you hit record.

What is actually happening

A mastered beat has been compressed and limited on purpose. The point of that process is to make the file as loud as it can be, which means pushing the loudest peaks up to just below 0 dBFS. That value is not a guideline, it is the top of the scale: a fixed point audio file, such as a 16 or 24 bit WAV, has no number available above it, and neither does the output of your audio interface.

Your voice is a second signal added on top of that. Two signals sum. If the beat alone is already close to the ceiling, the sum of beat plus voice goes over it, and the extra is simply flattened off. That is the crunch you are hearing, and it is happening at the master output, not on your vocal track. This is why the vocal meter can look perfectly healthy while the mix sounds damaged.

The ten second check

Confirm this is a headroom problem before you change anything, because the fix is different if it is not.

Give the beat headroom before you record

The whole fix is one decision: how far down does the beat go. Start around -10 to -14 dB and adjust from there. That puts the beat's peaks roughly in the -10 to -14 dBFS region, which leaves room for a vocal of similar level plus the sum of the two. Treat it as a starting range to check against your master meter, not a correct number. Write down what you used so the next session starts in the same place.

There are three places in REAPER to make that cut, and they are not interchangeable.

1. The beat track's volume fader

For a single stereo beat file this is the simplest and the easiest to undo. Use the volume control in the beat track's control panel and pull it down. It applies to everything on that track, so if you later swap in a different version of the beat, the setting is still there waiting.

2. Item volume

Right-click the beat item and open its item properties, where you can set a volume for that media item specifically. Item volume travels with the item, which is useful if you drag the beat into another project or keep several versions of it on one track at different levels. The trade-off is that it is less visible than a fader, so it is easy to forget it is there six weeks later.

3. A folder track as a beat bus

If the beat arrived as stems, or as separate drum, bass and melody files, do not pull each one down by hand. Put them all inside a folder track and use the folder parent as the beat bus, so one control moves the whole instrumental and keeps the internal balance the producer intended. Cockos describes REAPER's nested folder system as handling “routing, bussing, all in one step”, and this is exactly the case it is for. It also gives you one obvious place to put anything you later want applied to the beat and not the voice.

Then set the voice, in this order

With the beat sitting lower, the rest is ordinary and the order matters.

1. Set your recording level once and leave it. The beat's level has no effect on how hot your microphone signal is, and the two are easy to confuse. Aim for peaks comfortably below the ceiling, as covered in how to gain stage vocals in REAPER.
2. Build the headphone mix separately. What you hear while singing is a different thing from what the project is doing, and the beat usually needs to be louder in the phones than it is in the mix. The method is in how to set up a headphone mix for recording vocals.
3. Record, then judge the balance with everything playing. Check the master meter on the loudest chorus, not on a verse. If it is still touching the red, take another 2 to 3 dB off the beat rather than off the vocal.

When the beat only exists as a loud MP3

Often you cannot get a better file, and it is worth being clear about what that costs you. Pulling the beat down restores headroom. It does not restore dynamics. The limiting that flattened the beat is printed into the file and turning it down does not undo it, so a beat that sounded relentless at full volume will sound equally relentless, just quieter. Your voice will sit on top of it more easily, which is the win, but the beat will not open up.

If the producer offers one, ask for an unmastered or mix version with headroom left in it, sometimes sold as a tagless or track-out package. That is the version this problem does not happen with, and it is worth asking before you spend an evening working around the mastered one.

Before you commit a beat to the session at all, it is worth hearing it in context. REAPER’s Media Explorer previews a file at your project tempo and can route the preview through a real track so you hear it through your own FX, which is covered in how to use REAPER’s Media Explorer to audition and import beats and samples.

What this will not fix

Headroom is a prerequisite, not a mix.

• It will not make a squashed beat sound more dynamic or more spacious. That information is gone from the file.
• It will not make your voice sit in the mix. Once the levels are sane you still have balance, EQ and compression to do, and how loud the vocal should be in the mix is a separate question with its own answer.
• It will not rescue a take that was recorded too quietly or too hot in the first place. The beat's level and your input level are independent.
• It will not change how loud your finished upload is. Platform normalization sets that, which is also why a quieter session does not cost you anything. If your uploads have been coming back thinner than they sounded at home, that is covered in why your vocal sounds thin and quiet after uploading.

If it still is not working

1. You lowered the beat but left a limiter or maximizer on the master. Anything like that on the master will pull the beat straight back up and recreate the problem. Bypass the master chain while you are tracking.
2. The vocal track has a plugin adding gain. A compressor with makeup gain, or a saturator, can add more output than you realise. Bypass the vocal chain and check the raw levels first.
3. You are judging on a verse. Set levels against the loudest point in the song. Everything else will fit underneath it.
4. The beat is in a folder but you moved a child fader. Moving a child track inside a beat folder breaks the producer's internal balance. Put children back to unity and move only the parent.
5. It is distortion, not level. If the crunch stays after the master meter is comfortably clear, the damage is in the file or in the take, not in the arithmetic.
