Audio Mixer FAQ
What to prepare before combining vocals, music and other audio tracks.
What is the difference between mixing and joining audio?
Mixing layers recordings so they play at the same time, such as a voice over background music. Joining places clips one after another. This tool is intended for layered mixing, not for assembling a playlist or joining podcast segments end to end.
Can I combine a vocal recording with a backing track?
That is one of the intended uses. Prepare a separate vocal file and instrumental with matching timing, then add them to the workspace. You can listen to each source now; combined playback and the finished mix are not available yet.
How many files can I add, and which formats work?
Prepare 2–16 tracks for a mix, with each file no larger than 100 MB. The upload accepts MP3, WAV, FLAC, OGG, M4A and AAC, including different supported formats in the same list. Browser codec support can affect individual playback.
Do all tracks have to be the same length?
No. The planned mix uses the longest track as its duration. A shorter file contributes silence after it ends; it is not automatically repeated or stretched. Trim a long music bed beforehand if you want the mix to end earlier.
Can I move a track's start time or sync it to the beat?
Not in this workspace. There are no start-offset, beat-matching or timeline alignment controls. If a vocal needs to enter later or two recordings are out of sync, prepare their timing in an audio editor before adding them.
Can I lower the background music or balance track volumes?
There are no per-track mix volume controls or automatic balancing options here. Prepare the relative levels in your source files before mixing. The audio player's volume control only changes what you hear during preview; it does not change a mix setting.
Can I export the mix now, and what format will it use?
Mix rendering and export are not available yet. The planned output uses MP3 by default. At present, you can add, preview and remove sources, but you cannot download a combined recording.
Will my track list still be here after I refresh?
No. The current list is temporary and clears when the page reloads. Local files are used for browser preview without being uploaded by this workspace. Keep your original recordings so you can add them again.
