# AudioLDM 2
[](https://arxiv.org/abs/2308.05734) [](https://audioldm.github.io/audioldm2/) [](https://huggingface.co/spaces/haoheliu/audioldm2-text2audio-text2music)
This repo currently support Text-to-Audio (including Music), Text-to-Speech Generation and Super Resolution Inpainting.
## Change Log
- 2023-08-27: Add two new checkpoints!
- 🌟 **48kHz AudioLDM model**: Now we support high-fidelity audio generation! [](https://huggingface.co/spaces/haoheliu/AudioLDM_48K_Text-to-HiFiAudio_Generation)
- **16kHz improved AudioLDM model**: Trained with more data and optimized model architecture.
## TODO
- [x] Add the text-to-speech checkpoint
- [x] Open-source the [AudioLDM training code](https://github.com/haoheliu/AudioLDM-training-finetuning).
- [x] Support the generation of longer audio (> 10s)
- [x] Optimizing the inference speed of the model.
- [x] Integration with the Diffusers library (see [🧨 Diffusers](#hugging-face--diffusers))
- [ ] Add the style-transfer and inpainting code for the audioldm_48k checkpoint (PR welcomed, same logic as [AudioLDMv1](https://github.com/haoheliu/AudioLDM))
## Web APP
1. Prepare running environment
```shell
conda create -n audioldm python=3.8; conda activate audioldm
pip3 install git+https://github.com/haoheliu/AudioLDM2.git
git clone https://github.com/haoheliu/AudioLDM2; cd AudioLDM2
```
2. Start the web application (powered by Gradio)
```shell
python3 app.py
```
3. A link will be printed out. Click the link to open the browser and play.
## Commandline Usage
### Installation
Prepare running environment
```shell
# Optional
conda create -n audioldm python=3.8; conda activate audioldm
# Install AudioLDM
pip3 install git+https://github.com/haoheliu/AudioLDM2.git
```
If you plan to play around with text-to-speech generation. Please also make sure you have installed [espeak](https://espeak.sourceforge.net/download.html). On linux you can do it by
```shell
sudo apt-get install espeak
```
### Run the model in commandline
- Generate sound effect or Music based on a text prompt
```shell
audioldm2 -t "Musical constellations twinkling in the night sky, forming a cosmic melody."
```
- Generate sound effect or music based on a list of text
```shell
audioldm2 -tl batch.lst
```
- Generate speech based on (1) the transcription and (2) the description of the speaker
```shell
audioldm2 -t "A female reporter is speaking full of emotion" --transcription "Wish you have a good day"
audioldm2 -t "A female reporter is speaking" --transcription "Wish you have a good day"
```
Text-to-Speech use the *audioldm2-speech-gigaspeech* checkpoint by default. If you like to run TTS with LJSpeech pretrained checkpoint, simply set *--model_name audioldm2-speech-ljspeech*.
## Random Seed Matters
Sometimes model may not perform well (sounds weird or low quality) when changing into a different hardware. In this case, please adjust the random seed and find the optimal one for your hardware.
```shell
audioldm2 --seed 1234 -t "Musical constellations twinkling in the night sky, forming a cosmic melody."
```
## Pretrained Models
You can choose model checkpoint by setting up "model_name":
```shell
# CUDA
audioldm2 --model_name "audioldm2-full" --device cuda -t "Musical constellations twinkling in the night sky, forming a cosmic melody."
# MPS
audioldm2 --model_name "audioldm2-full" --device mps -t "Musical constellations twinkling in the night sky, forming a cosmic melody."
```
We have five checkpoints you can choose:
1. **audioldm2-full** (default): Generate both sound effect and music generation with the AudioLDM2 architecture.
2. **audioldm_48k**: This checkpoint can generate high fidelity sound effect and music.
3. **audioldm_16k_crossattn_t5**: The improved version of [AudioLDM 1.0](https://github.com/haoheliu/AudioLDM).
4. **audioldm2-full-large-1150k**: Larger version of audioldm2-full.
5. **audioldm2-music-665k**: Music generation.
6. **audioldm2-speech-gigaspeech** (default for TTS): Text-to-Speech, trained on GigaSpeech Dataset.
7. **audioldm2-speech-ljspeech**: Text-to-Speech, trained on LJSpeech Dataset.
We currently support 3 devices:
- cpu
- cuda
- mps ( Notice that the computation requires about 20GB of RAM. )
## Other options

The checkpoint you gonna use
-d DEVICE, --device DEVICE
The device for computation. If not specified, the script will automatically choose the device based on your environment. [cpu, cuda, mps, auto]
-b BATCHSIZE, --batchsize BATCHSIZE
Generate how many samples at the same time
--ddim_steps DDIM_STEPS
-dur DURATION, --duration DURATION
The duration of the samples
The sampling step for DDIM
-gs GUIDANCE_SCALE, --guidance_scale GUIDANCE_SCALE
Guidance scale (Large => better quality and relavancy to text; Small => better diversity)
-n N_CANDIDATE_GEN_PER_TEXT, --n_candidate_gen_per_text N_CANDIDATE_GEN_PER_TEXT
Automatic quality control. This number control the number of candidates (e.g., generate three audios and choose the best to show you). A Larger value usually lead to better quality with
heavier computation
--seed SEED Change this value (any integer number) will lead to a different generation result.
```
## Hugging Face 🧨 Diffusers
AudioLDM 2 is available in the Hugging Face [🧨 Diffusers](https://github.com/huggingface/diffusers) library from v0.21.0
onwards. The official checkpoints can be found on the [Hugging Face Hub](https://huggingface.co/cvssp/audioldm2#checkpoint-details),
alongside [documentation](https://huggingface.co/docs/diffusers/main/en/api/pipelines/audioldm2) and
[examples scripts](https://colab.research.google.com/github/sanchit-gandhi/notebooks/blob/main/AudioLDM-2.ipynb).
The Diffusers version of the code runs upwards of **3x faster** than the native AudioLDM 2 implementation, and supports
generating audios of arbitrary length.
To install 🧨 Diffusers and 🤗 Transformers, run:
```bash
pip install --upgrade git+https://github.com/huggingface/diffusers.git transformers accelerate
```
You can then load pre-trained weights into the [AudioLDM2 pipeline](https://huggingface.co/docs/diffusers/main/en/api/pipelines/audioldm2),
and generate text-conditional audio outputs by providing a text prompt:
```python
from diffusers import AudioLDM2Pipeline
import torch
import scipy
repo_id = "cvssp/audioldm2"
pipe = AudioLDM2Pipeline.from_pretrained(repo_id, torch_dtype=torch.float16)
pipe = pipe.to("cuda")
prompt = "Techno music with a strong, upbeat tempo and high melodic riffs."
audio = pipe(prompt, num_inference_steps=200, audio_length_in_s=10.0).audios[0]
scipy.io.wavfile.write("techno.wav", rate=16000, data=audio)
```
Tips for obtaining high-quality generations can be found under the AudioLDM 2 [docs](https://huggingface.co/docs/diffusers/main/en/api/pipelines/audioldm2#tips),
including the use of prompt engineering and negative prompting.
Tips for optimising inference speed can be found in the blog post [AudioLDM 2, but faster ⚡️](https://huggingface.co/blog/audioldm2).
