Spire Multitrack Recorder

Before you start

Spire is a multitrack recording app designed for iOS devices. The main workflow happens locally on the iPhone or iPad: audio is recorded onto the device, and projects are stored in the app. Check that your device has enough free storage before recording long takes. For the most predictable experience, update Spire to the version available for your current iOS release, close other audio-heavy apps, and connect headphones when monitoring. If you plan to import an existing audio file, keep that file accessible on the device first.

Step-by-step instructions

Start by opening Spire and creating a new song or project. On the main project screen, add a track for each part you want to record, such as a vocal, guitar, keyboard or drum machine. Give each track a clear name so it is easier to find later.

Select the track you want to record and check the input source. Depending on your setup, the source may be the device microphone, a headset microphone, or an audio interface connected through a compatible adapter. Tap the record enable or arm control for the track, then use the transport record button to start capture. Play or speak at a steady distance from the microphone and watch the level indicator for clipping.

Record each part separately, or enable more than one track when your input routing supports it. You can stop after the first take, move the playhead back, arm a new track and record the next layer while listening to the existing tracks. This is the standard way to build a multitrack recording without needing a separate mixer.

After recording, use the editor to trim unwanted silence, adjust track volume or pan, and move regions if needed. Some versions label these controls differently, so look for the track header and edit icons rather than relying on a fixed menu path. Save or apply each change as you go, and avoid deleting the original take until the edited version sounds correct.

To add a previously recorded file, use the import or add audio option for the project. The app then places the imported audio on a track, where you can align it with the other parts. Keep the original file as a backup in case alignment needs to be repeated.

When the project is ready, choose the export or share command. Select the output format and quality available in your version, then choose where to save the file on the device or through an available sharing destination. Before exporting a long project, confirm you have enough free space for the resulting file.

Check the output

Play back the exported audio outside Spire or in the app's playback view. Listen for tracks that are missing, too quiet, clipped or out of sync. Compare the exported length with the project length and check that the file opens in the destination app. If the result is intended for a video call or camera workflow, test it in that final context before deleting the project.

For a mixed export, the output is a single stereo or mono audio file, not the separate multitrack stems. Exact quality and format options depend on the installed Spire version, so review the available choices during export instead of assuming a particular sample rate or bit depth.

Common problems and next steps

If a track cannot hear the microphone, check whether the app has permission to use the microphone and whether the correct input is selected for that track. A headset or interface may be recognized only after it is connected before the app is opened.

If recordings sound clipped or distorted, reduce the input level or move farther from the microphone. Very low recorded levels are easier to correct than tracks that were clipped during capture.

If the export is not visible in another app, check the sharing destination or file location chosen during export. If a project becomes slow, close other apps, free device storage and restart Spire. For version-specific export limits or account features, use the current information shown in the app rather than treating third-party descriptions as exact for every release.
