Audio Bitrate - Weather you use CBR or VBR, choose the highest bitrate you can afford (at the expense of a bigger file size) for the best audio quality.Use CBR when you want a constant bitrate throughout. However, VBR may also introduce playback/seek issues due to the variability in bitrate. Choose VBR when you want to optimize file size and quality (the encoder will use a higher bitrate for complex content while saving bitrate from areas that do not need as much data. Audio Rate Control - You can either use VBR (Variable Bit Rate) or CBR (Constant Bit Rate).Doing so will also unlock most of the following advanced options. Audio Codec - Select the MP3 (MPEG-1 Audio Layer III) codec for the best MP3 quality.Use our Advanced Settings to perfectly convert any file to MP3 format.
