Usage

You can download mp3s from youtube using yt-dlp:

yt-dlp --audio-format mp3 --extract-audio --no-playlist --audio-quality 0 <youtube-link> -o <save-path>

You can then transcribe using the cli:

aria-amt transcribe \
    medium-double \
    <path-to-checkpoint> \
    -load_path <path-to-audio> \
    -save_dir <path-to-save-dir> \
    -bs 1 \
    -compile

If you want to do batch transcription, use the -load_dir flag and adjust -bs accordingly. Compiling and may take some time, but provides a significant speedup. Quantizing (-q8 flag) further speeds up inference when the -compile flag is also used.

NOTE: Int8 quantization is only supported on GPUs that support BF16.
