What does Audio Merger do?
Join multiple audio files into one track, with optional crossfade.
Audio Merger accepts MP3, WAV, OGG, M4A, AAC, FLAC and WEBM files — and you can add several at once, and produces MP3 and WAV output.
Your MP3, WAV, OGG, M4A, AAC, FLAC and WEBM files are processed locally in your browser — they are never uploaded to our servers.
