Perguntas frequentes
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.
Posso instalar o Merge Audio como um aplicativo da web e usá-lo offline?
