Files are joined in the order shown below.

Processing runs locally in your browser; files are not uploaded.

Combine recordings, songs, voice notes, and other supported audio files even when their source formats differ. Arrange the list, trim each track from its waveform, and insert pauses of the length you need.

Choose the output format, sample rate, and mono or stereo channels before joining. Processing stays in this browser tab, so the selected files are not uploaded by this tool.

Can I add silence between tracks?

Which output formats are available?

You can export the joined audio as MP3, WAV, M4A, AAC, OGG, Opus, FLAC, or AIFF and choose the sample rate and mono or stereo channels.

Are my audio files uploaded?
