How to record a band rehearsal on a Mac

Tested on macOS 26.4.1 (Tahoe), Apple M3 Max, 3 Sept 2026. Updated 2026-09-03.

You record a band rehearsal on a Mac either as one stereo file (the PA mixer's REC out, or a stereo room mic pair, into a 2-input USB interface) or as a multitrack session through an interface with 4 to 8 inputs into a DAW. Stereo is enough to review songs and arrangements and costs 0.97 GB per hour at 24-bit 48 kHz; multitrack is for a mix you will release.

Should you record a rehearsal in stereo or multitrack?

Decide by what the recording is for. To hear whether the bridge works, whether the drummer rushes, and to send a rough to the singer, a single stereo file is right: one device, one take, nothing to mix, and it plays on a phone. To produce a track you will release, you need each instrument on its own channel so you can balance and edit later, which means a multi-input interface, a DAW session, and an hour of mixing per song.

The cost difference is real. Stereo works with a Scarlett 2i2 4th Gen ($224.99, two inputs) or a Behringer UMC202HD ($58 at Thomann US, two combo inputs, 24-bit up to 192 kHz). Multitrack needs a Scarlett 8i6 3rd Gen ($309.99, two mic preamps plus four line inputs) or a Behringer UMC404HD (four combo inputs, 24-bit 192 kHz), and for a five piece with a miked kit even eight inputs run out fast.

Most bands should record stereo every rehearsal and multitrack only when a song is ready. This page covers the stereo route in detail and the multitrack route as far as the interface and channel choice; DAW mixing is a different topic.

What is the best stereo source: mixer out or a room mic?

If the band plays through a PA with a mixer, take the mixer's REC OUT, a spare stereo AUX, or the MAIN out into two line inputs of the interface. That gives you what the mixer sees: vocals and anything else miked or DI'd, at a controlled level. What it misses is the backline: guitar amps and drums that are not in the PA are only faintly present through bleed. In a small room that produces a vocal-heavy recording with distant drums.

A stereo room mic pair (two small diaphragm condensers on a bar, or a single stereo mic) a few meters in front of the band captures the balance the room actually has, drums and amps included, but no control over that balance and more room sound. For rehearsal review this is usually the more honest recording.

The compromise that works in practice: a room pair on inputs 1-2 (mic preamps, phantom power on) and the mixer REC out on line inputs 3-4, recorded as "all channels" into one 4-channel file, then pick or blend afterwards. This is exactly the channel-pair problem covered in record a DJ mix with an audio interface: the recorder must let you choose pairs or all channels, otherwise it records inputs 1-2 and nothing else.

How do you set levels for a loud band?

A rehearsal room is louder than you think and a snare hit peaks far above the average. Set gain during the loudest song, not during the sound check chat.

1. Have the band play the loudest section for 30 seconds.
2. Raise each preamp until the interface's clip indicator flickers, then back off so it never lights again; peaks should end up around -6 dBFS in the recorder.
3. For a mixer feed, set the interface line input (if it has gain) or the mixer's REC or AUX level, never the main fader that feeds the PA.
4. Record 24-bit. With 24-bit you can sit peaks at -12 dBFS and still have a clean file to normalize; 16-bit at that level leaves far less margin.

Condensers in front of a drum kit can overload their own electronics before the preamp clips; if the recording distorts with the gain already low, engage the mic's pad or move it back. More on diagnosing distortion in why a Mac recording sounds distorted.

What do you need to record a rehearsal multitrack on a Mac?

One interface with enough inputs, a DAW, and the same sample rate everywhere. Count inputs before buying: kick, snare, two overheads, bass DI, guitar amp mic, vocal is seven, so a 4-input box already forces submixing. Two cheaper interfaces can be combined in Audio MIDI Setup as an aggregate device, but Apple's guide notes that "All devices in the aggregate device need to have the same sample rate" and that drift correction (resampling) is required for devices without hardware sync; a single 8-input interface avoids that and is more reliable for a two hour session. Steps for the aggregate route are in how to create an aggregate device.

Disk space scales with channels: a stereo 24-bit 48 kHz file is 16.5 MB per minute on the author's Mac, so eight channels are roughly four times that, about 4 GB per hour. A two hour rehearsal multitracked is 8 GB; keep 20 GB free.

The DAW records each input to its own track and saves a project. A simple recorder that captures "all channels" of the interface gives you one multichannel file instead, which you can import into a DAW later; that is fine for archiving but less convenient than a session.

All devices in the aggregate device need to have the same sample rate.

Where AirCheck fits

AirCheck ($39, macOS 14 or newer) fits the stereo and the 4-channel review recordings: select the interface, pick Ch 1-2 for the room pair, Ch 3-4 for the mixer feed, or all channels for both in one file, and it records 24-bit for as long as the disk allows, exporting to WAV or MP3 320 kbps when the take ends. The 5 second watchdog restarts capture into the same file if a USB hub hiccups mid song. It is not a DAW: no per-track editing, no mixing, no overdubs.

When you do not need it: For a proper multitrack session that you will mix, use GarageBand (free) or Logic Pro with the interface directly; a single multichannel file from a plain recorder is only an archive.

Questions people ask

Can I record a band rehearsal with just the Mac's built-in microphone?

You can, and for a first listen it is better than nothing, but the built-in mic compresses and distorts at rehearsal volume. Even a $58 two-input interface with one cheap dynamic mic in the room is a large step up.

How many inputs does an interface need to record a band?

Two for a stereo review recording (mixer out or a room pair). Four to eight for multitrack; count the sources you want separate (kick, snare, overheads, bass, guitar, vocal) and buy at least that many. Two interfaces can be aggregated in Audio MIDI Setup at the same sample rate.

What sample rate should I use for a rehearsal recording?

48 kHz at 24-bit. It matches video if you ever cut rehearsal footage, costs 16.5 MB per minute in stereo, and every interface listed here supports it. Make sure the DAW, the interface and any aggregate device all use the same rate.

How do I record a rehearsal so everyone can listen on their phone?

Record stereo at 24-bit, then export MP3 320 kbps, which is 2.4 MB per minute, about 290 MB for a two hour rehearsal. Share the MP3 and keep the 24-bit master.
