The recorder also has an 'MP3' recording option, which is not a professional recording format, so the recording quality can only reach 128kbps. Users can choose according to their needs. Troubleshooting The default format of the recording is WAV. If you prefer MP3, you need to manually set it to MP3. If the recorder freezes: press and hold the power button for about 20 seconds to restart it, then plug it into the computer to activate it. Do not format the recorder on iOS.
