FAQ
Is my audio uploaded to a server?
No. The MP3 encoder runs inside your browser, so your recording stays on your device the whole time.
Which bitrate should I choose?
192 kbps sounds great for most music and podcasts. Choose 320 kbps if you want it as close to the original as MP3 allows, or 128 kbps for voice and small files.
What kinds of WAV files work?
8, 16, 24 and 32-bit PCM and 32-bit float WAV, mono or stereo. High sample rates like 96 kHz are converted to 48 kHz, the highest rate MP3 supports.
Is there a file size limit?
No fixed limit. Long recordings (an hour or more) depend on your device’s memory and can take a minute to encode.
