Preguntas frecuentes
How do I concatenate audio files?
Choose the files, put them in order and download: they are joined end to end into one WAV. Pick a gap or a crossfade if you want space or a smooth blend between them.
Can I merge different formats?
Yes. Mix MP3, WAV, M4A, OGG and more — everything is decoded and combined into one WAV file.
Is there a file size limit?
Only your device’s memory. An hour of stereo audio uses about 600 MB while merging.
Are my files uploaded?
No. Merging happens entirely in your browser.
