No upload endpoint is used; speed depends on your device and browser support.
Frequently asked questions
Which formats are supported?
Actual decoding depends on the browser. WAV, MP3, and OGG are common; M4A support varies by browser.
Is my audio uploaded?
No. File API reads the file in this tab, and the exported result is a local Blob.
Can I export MP3?
Yes. MP3 is encoded in the browser; WAV is the faster choice on lower-resource devices.
