##### Add YouTube video to library (auto-download)
```bash
python polymath.py -a n6DAqMFe97E
python -m polymath -a n6DAqMFe97E
```
##### Add audio file (wav or mp3)
```bash
python polymath.py -a /path/to/audiolib/song.wav
python -m polymath -a /path/to/audiolib/song.wav
```
##### Add multiple files at once
```bash
python polymath.py -a n6DAqMFe97E,eaPzCHEQExs,RijB8wnJCN0
python polymath.py -a /path/to/audiolib/song1.wav,/path/to/audiolib/song2.wav
python polymath.py -a /path/to/audiolib/
python -m polymath -a n6DAqMFe97E,eaPzCHEQExs,RijB8wnJCN0

python -m polymath -a /path/to/audiolib/
```
Songs are automatically analyzed once which takes some time. Once in the database, they can be access rapidly. The database is stored in the folder "/library/database.p". To reset everything, simply delete it.

### 2. Quantize songs in the Polymath Library
##### Quantize a specific songs in the library to tempo 120 BPM (-q = database audio file ID, -t = tempo in BPM)
```bash
python polymath.py -q n6DAqMFe97E -t 120
python -m polymath -q n6DAqMFe97E -t 120
```
##### Quantize all songs in the library to tempo 120 BPM
```bash
python polymath.py -q all -t 120
python -m polymath -q all -t 120
```
##### Quantize a specific songs in the library to the tempo of the song (-k)
```bash
python polymath.py -q n6DAqMFe97E -k
python -m polymath -q n6DAqMFe97E -k
```
Songs are automatically quantized to the same tempo and beat-grid and saved to the folder “/processed”.

### 3. Search for similar songs in the Polymath Library
##### Search for 10 similar songs based on a specific songs in the library (-s = database audio file ID, -sa = results amount)
```bash
python polymath.py -s n6DAqMFe97E -sa 10
python -m polymath -s n6DAqMFe97E -sa 10
```
##### Search for similar songs based on a specific songs in the library and quantize all of them to tempo 120 BPM
```bash
python polymath.py -s n6DAqMFe97E -sa 10 -q all -t 120
python -m polymath -s n6DAqMFe97E -sa 10 -q all -t 120
```
##### Include BPM as search criteria (-st)
```bash
python polymath.py -s n6DAqMFe97E -sa 10 -q all -t 120 -st -k
python -m polymath -s n6DAqMFe97E -sa 10 -q all -t 120 -st -k
```
Similar songs are automatically found and optionally quantized and saved to the folder "/processed". This makes it easy to create for example an hour long mix of songs that perfectly match one after the other.

### 4. Convert Audio to MIDI
##### Convert all processed audio files and stems to MIDI (-m)
```bash
python polymath.py -a n6DAqMFe97E -q all -t 120 -m
python -m polymath -a n6DAqMFe97E -q all -t 120 -m
```
Generated Midi Files are currently always 120BPM and need to be time adjusted in your DAW. This will be resolved [soon](https://github.com/spotify/basic-pitch/issues/40). The current Audio2Midi model gives mixed results with drums/percussion. This will be resolved with additional audio2midi model options in the future.
