Open Source Multitrack Recording Software

Before you start

Open source multitrack recording software runs locally on your computer, so you need enough free disk space for uncompressed or lightly compressed audio and a reliable audio input. A USB audio interface or mixer is useful when you want separate tracks for a microphone, instrument or call participant, but many programs also record individual applications and virtual inputs without extra hardware. Check whether the version you install supports your operating system and whether you need an audio driver or plugin package before recording.

Step-by-step instructions

Start with a recording-oriented audio editor or digital audio workstation that supports multiple tracks. Install the program from its official package or repository, then open its audio settings and select the device driver, sample rate and buffer size. Use the lowest buffer that stays stable while recording; a larger buffer may be safer on slower computers.

Create and arm separate tracks

• Create one track for each source you want to isolate, such as microphone, desktop audio, a video call participant or a connected camera audio input.
• Open each track's input selector and choose the matching device, input channel or application source.
• Arm every track you are about to record. Unarmed tracks may not capture audio depending on the application.
• Check the input meters with the transport stopped. A healthy level usually stays below the top red area, leaving headroom for louder moments.
• Set the recording format and destination folder in the project settings or export preferences.
• Press Record, then Export or Mixdown when finished and save the separate stems if you still need them for editing.

Important settings and version differences

Some applications label audio inputs as Jack, ALSA, ASIO, WASAPI or Core Audio depending on the platform. Version differences can change where loopback or virtual device routing appears, so use the current manual for your installed release rather than older screenshots. Keep a copy of the original take and avoid destructive edits until you have exported a usable version.

Check the output

Play back the exported file and confirm that each source is present at the intended volume and that the separate tracks remain isolated where needed. Inspect the file details for sample rate, bit depth and channel count, and compare them with the settings you selected. For video-based workflows, confirm that audio sync stays consistent from the beginning to the end of the recording.

Common problems and next steps

If a track is silent, check whether it was armed and whether the correct input was selected before recording. Distorted audio often means the input was too hot, while a thin or distant sound may mean the wrong device or channel was used. When tracks become misaligned with video, align them using the beginning transient or a visible marker, then adjust one track at a time.

Recording separate sources without extra hardware

You can record a microphone on one track and system audio on another by enabling the appropriate loopback or application capture source where the program supports it. For a remote participant, route the call application to its own track instead of mixing it with your microphone. Some setups need a virtual audio cable or routing tool, but the exact approach depends on the recording software and operating system.

Preparing audio from a camera or video call

Select the camera or video call device only when it is available as an audio input in the current program. For a recorded video call, avoid monitoring the same source through speakers into the microphone because that can introduce echo into the multitrack session. Record a short test take first and check each track before capturing the full call.
