Software for Live Multitrack Recording

Before you start

Check whether your audio interface or mixer exposes each input as a separate USB channel. Live multitrack recording software records these channels individually, but the hardware driver must present them to the operating system first. Some compact mixers send only a stereo mix over USB even when they can mix many inputs locally.

Close other applications that may claim the audio device. On desktop systems, only one program can normally access an audio interface at a time unless you use a low-level driver such as ASIO on Windows or Core Audio on macOS.

Step-by-step instructions

The exact procedure depends on the recording application, but the setup order is usually the same.

• Connect the audio interface or mixer before starting the recording program. Install the relevant driver or control app first when the manufacturer provides one. Select the device in the recording program's audio settings. Create one track for each input channel that should be recorded separately. Assign each track to the matching hardware input rather than leaving tracks set to a stereo mix. Arm the tracks for recording. Set the sample rate to match the hardware and the project. Choose a recording location on a drive with enough free space, because separate audio tracks increase file size. Start recording before the performance and monitor the track meters instead of making changes during the take.

In apps with project templates, configure input routing once and save the template. Version differences can move audio settings between Preferences, Project Settings and Audio Setup, so use the current documentation for your version when an option is not where you expect it.

Check the output

During the test pass, confirm that each armed track shows activity only for its assigned source. A channel mapped incorrectly may appear silent or duplicate another input. After stopping, listen to each recorded file in isolation before mixing. Check the file format and split settings if your software creates one combined file instead of separate files per track.

Confirm that the recording length matches the performance and that no tracks were created as empty placeholders. Multitrack recording does not improve a poor input, so verify microphone gain and camera audio routing before relying on a longer take.

Common problems and next steps

If the software only receives a stereo feed, check the interface control panel for a USB routing or mode setting. Some devices must be switched from stereo mix mode to multichannel mode before individual inputs appear.

When tracks gradually drift apart, the interface and software may be using different clock sources. Set one device as the clock master and make the sample rate explicit in both places.

If monitoring causes an echo, mute the track output while recording or use direct monitoring from the interface. For video calls, route only the intended mix into the call and keep the multitrack capture separate from the call audio path.

For a mobile or browser-based workflow, confirm first whether the tool records locally or processes audio through an online service. Do not assume that a web app can access all hardware channels or that files remain only on the device.
