Audio Merger
Join two or more compatible audio files in the selected order and export a new 16-bit PCM WAV without uploading them.
How merging works
Each source is decoded locally in your browser. Build 104 appends decoded samples in selection order, then creates a new PCM WAV file. Your originals remain unchanged.
Compatibility limitation
This browser foundation requires every file to have the same decoded sample rate and channel count. It does not silently resample or remix mismatched inputs because doing so would change the signal without an explicit verified workflow.
Quality and recommendations
Merging does not restore quality lost in MP3/AAC sources. If clips have different loudness, use Gain & Peak Normalize before merging. Hard joins can click when waveforms meet away from zero; a crossfade workflow may be added in a later verified build.
Privacy
Files are processed locally in this Build 104 workflow. No upload endpoint is required.
