Audio Merging FAQ
Can I merge audio files in different formats?
Yes. Files in different formats are first converted to the target format, then joined in order.
How many audio files can I merge?
There's no fixed limit — it depends on your browser's available memory.
How is the merged audio quality?
The default 192 kbps bitrate sounds clear; you can customize it in the settings — higher bitrates sound better.
Can I change the order of the files?
Yes. After uploading, reorder the list to set the final sequence.
Can I combine multiple recordings into one?
Yes. Upload the recordings, arrange the order, and merge them into a single audio file in one click.
