Knowledge Base
Upload your MP3 and select an output bitrate. 128kbps is good for voice and streaming. 192kbps balances quality and size for music. 320kbps preserves near-original quality.
For podcasts and voice: 64-96kbps. For music streaming: 128-192kbps. For archival quality: 320kbps. Higher bitrate means larger file size but better audio quality.
