 # aria-amt
-MIDI conditioned automatic music transcription
+
+Efficient and robust implementation of seq-to-seq automatic piano transcription.
+
+## Install 
+
+Requires Python 3.11
+
+```
+git clone https://github.com/EleutherAI/aria-amt.git
+cd aria-amt
+pip install -e .
+```
+
+Download the preliminary model weights:
+
+```
+wget https://storage.googleapis.com/aria-checkpoints/amt/small-0.safetensors
+```
+
+## Usage
+
+You can download mp3s from youtube using [yt-dlp](https://github.com/yt-dlp/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 \
+    small-final \
+    <path-to-checkpoint> \
+    -load_path <path-to-audio> \
+    -save_dir <path-to-save-dir> \
+    -bs 1 \
+    -compile \
+    -q8
+```
+
+If you want to do batch transcription, use the `-load_dir` flag and adjust `-bs` accordingly. Compiling may take some time, but provides a significant speedup.
+
+NOTE: Currently only bf16 is supported.
