Tutorial - AudioCraft

Let's run Meta's AudioCraft , to produce high-quality audio and music on Jetson!

What you need

  1. One of the following Jetson devices:

    Jetson AGX Orin (64GB) Jetson AGX Orin (32GB) Jetson Orin Nano (8GB)

  2. Running one of the following versions of JetPack :

    JetPack 5 (L4T r35.x)

  3. Sufficient storage space (preferably with NVMe SSD).

    • 10.7 GB for audiocraft container image
    • Space for checkpoints

  4. Clone and setup jetson-containers : 

    git clone https://github.com/dusty-nv/jetson-containers
bash jetson-containers/install.sh

How to start

Use run.sh and autotag script to automatically pull or build a compatible container image. 

jetson-containers run $(autotag audiocraft)

The container has a default run command ( CMD ) that will automatically start the Jupyter Lab server.

Open your browser and access http://<IP_ADDRESS>:8888 .

The default password for Jupyter Lab is nvidia .

Run Jupyter notebooks

AudioCraft repo comes with demo Jupyter notebooks.

On Jupyter Lab navigation pane on the left, double-click demos folder.

AudioGen demo

Run cells with Shift + Enter , first one will download models, which can take some time.

Info

You may encounter an error message like the following when executing the first cell, but you can keep going. 

A matching Triton is not available, some optimizations will not be enabled.
Error caught was: No module named 'triton'

In the Audio Continuation cells, you can generate continuation based on text, while in Text-conditional Generation you can generate audio based just on text descriptions.

You can also use your own audio as prompt, and use text descriptions to generate continuation: 

prompt_waveform, prompt_sr = torchaudio.load("../assets/sirens_and_a_humming_engine_approach_and_pass.mp3") # you can upload your own audio
prompt_duration = 2
prompt_waveform = prompt_waveform[..., :int(prompt_duration * prompt_sr)]
output = model.generate_continuation(prompt_waveform.expand(3, -1, -1), prompt_sample_rate=prompt_sr,descriptions=[
        'Subway train blowing its horn',   # text descriptions for continuation
        'Horse neighing furiously',
        'Cat hissing'
], progress=True)
display_audio(output, sample_rate=16000)

MusicGen and MAGNeT demos

The two other jupyter notebooks are similar to AuidioGen, where you can generate continuation or generate audio, while using models trained to generate music.
