 The audio streams in converted (video) files from `yt` will generally be of higher quality compared to [online alternatives](https://www.google.nl/search?q=youtube+to+mp3+online), while maintaining a comparable file size. This is achieved by preferring WAV/OPUS source streams, and by converting using the [Fraunhofer FDK AAC codec library](https://trac.ffmpeg.org/wiki/Encode/AAC#fdk_aac) at a bitrate of 256kbit/s (sufficient to encode a full 44.1kHz stream using `libfdk_aac` without losing detail at higher frequencies).
