audio format
all formats but "best" are converted from the source format, there will be some quality loss. when "best" format is selected, the audio is kept in its original format whenever possible.
audio bitrate
bitrate is applied only when converting audio to a lossy format. titty.tools can't improve the source audio quality, so choosing a bitrate over 128kbps may inflate the file size with no audible difference. perceived quality may vary by format.
