Traditionally, training machine learning models for audio classification requires large amounts of real-world data, which can be expensive, time-consuming, and difficult to obtain. Machine-learning models trained on synthetic data can outperform models trained using real data in certain circumstances. So, how can synthetic data be generated? This is where Generative AI comes into play. Generative AI offers a powerful solution by allowing us to create synthetic data sets that are highly realistic and diverse. This synthetic data can be generated quickly and easily, allowing for faster and more efficient model development.
The goal of this project is to demonstrate how we can develop an Audio Classification system that can distinguish between different classes. To achieve this, we will be using OpenAI's ChatGPT, Meta's AudioCraft, Nvidia's Jetson AGX Orin Developer Kit 64 GB andEdge Impulse platform to train our model and then deploy it to an edge device such as Arduino GIGA R1 WiFi.
Our classes are:
- Speech
- Music
- NoiseBelow flow diagram can better explain the overall architecture of the project.
This flow diagram illustrates the process for audio classification on the Arduino GIGA R1 using synthetic data generated with Meta's Audiocraft and ChatGPT. The process consists of three stages: data processing, training, and deployment. In the data processing stage, ChatGPT is used to generate text prompts for three different classes: noise, speech, and music. Then, Meta's Audiocraft is utilized on the NVIDIA Jetson AGX Orin 64GB Developer Kit to generate a synthetic dataset. In the training stage, the Edge Impulse cloud platform is used to train the model. Finally, in the deployment stage, the trained model is deployed on the Arduino GIGA R1.
Text prompts generation using ChatGPTI plan to leverage the capabilities of ChatGPT to generate diverse text prompts for various classes. The prompt utilized to gather examples from ChatGPT is as follows:
I am creating a dataset of synthetic audio data for an audio classification task, which generates audio from text prompts. The first class in this dataset is background noise. Here is a list of examples for this class:
A hammer is hitting a wooden surface,
A noise of nature,
The sound of waves crashing on the shore,
A thunderstorm in the distance,
Traffic noise on a busy street,
The hum of an air conditioning unit,
Birds chirping in the morning,
The sound of a train passing
Could you please provide other 100 examples?Please note that these are just examples. You can use these prompts as a starting point, or you can create your own prompts that are specific to your needs.
Here are examples of the different types of output generated by ChatGPT for each category.
Below is list of a variety of speech samples encompassing diverse genders, emotions, and speaking styles. These samples can be in the form of dialogues, monologues, narratives, or any other format that effectively showcases the range of human speech.

Hissing of a distant steamboat on a riverThese are just examples, and the prompts can be further customized to generate more specific and detailed outputs from ChatGPT. The possibilities are endless when it comes to utilizing ChatGPT for creative text prompt generation.
Dataset Generation for Audio Classification using AudioCraftTo classify audio based on different categories, we will need to gather some sample WAV files of music, background noise, and speech classes. This will enable the system to differentiate between the three categories. Here, I will be using Audiocraft developed by Meta to generate from our prompts wav audio files.
AudioCraft is a powerful tool in synthetic music generation, and sound effects. It utilizes three AI models developed by Meta AI:
- MusicGen: Generates music based on textual prompts.
- AudioGen: Creates sound effects from simple descriptions.
- EnCodec: Compresses and tokenizes audio data for efficient processing.
To use AudioCraft, you will need a standalone computer with a GPU. I have the Nvidia Jetson AGX Orin Developer Kit 64GB, which is suitable for this purpose. Additionally, you can consider using Google Colab if you prefer a cloud-based solution. The Nvidia Jetson AGX Orin Developer Kit 64GB offers the following features:
- AI Performance: 275 TOPS
- GPU: 2048-core NVIDIA Ampere architecture GPU with 64 Tensor Cores
- CPU: 12-core Arm® Cortex®-A78AE v8.2 64-bit CPU
- Memory: 64GB 256-bit LPDDR5 204.8GB/s
- Storage: 64GB eMMC 5.1
- Power: 15W - 60W (with the Enclosure accessory)
Nvidia Jetson AGX Orin Developer Kit

MusicGen comes with four pretrained models:
- facebook/musicgen-small: A 300M model, for text to music generation only.
- facebook/musicgen-medium: A 1.5B model, for text to music generation only.
- facebook/musicgen-melody: A 1.5B model, for text to music and text+melody to music.

However, keep in mind that the model is quite large, so it may take some time to generate, especially if you don't have a GPU. Once the wav audio samples have been collected, they can be fed into the neural network to initiate the training process.
Model Training using Edge Impulse platformNow we can simply upload these wav files to the Edge Impulse Studioin order to train our model. Edge Impulseoffers an end-to-end solution for deploying models on TinyML devices. Here I assume that you are familiar with Edge Impulse
Create a new project. Select the Data acquisition tab and select upload data. Make sure that under the label option, you have mentioned the Label name. Upload your wav files.
In total, I have gathered 1 hour 52 minutes and 30 seconds worth of data that can be categorized into three distinct classes.
- Speech class
- Background noise class
- Music
Also, you can visualize complex datasets in Edge Impulse. The data explorer is a visual tool to explore your dataset, find outliers or mislabeled data, and to help label unlabeled data. I highly recommend to use this great feature.
Once you have set up all of your classes and are happy with your datasets, it is time to train the model. Navigate to Create Impulse on the left navigation menu.
I settled with the following parameters:
- Window Size = 2000 ms
- Window Increase = 300 ms
- Audio(MFE)
- Classification
Click Save Impulse.
Then navigate to MFE. In this step we will generate the features from the input data. Features are unique properties that will be used by the classification algorithm to classify audio.
Once you're done playing with the feature explorer, click on the Classifier item in the left navigation menu.
For this project, the number of training cycles was set to 50 and the learning rate was set to 0.0005.
Train the model by pressing the Start training button. This process might take around 10-20 minutes, depends on your data set sizes.
After training is complete, Edge Impulse Studio will display the performance of the model, a confusion matrix, feature explorer, and on-device performance details.
The accuracy of 90.7% is pretty good for the training set.
Then, go to the Deployment tab of the Edge Impulse. Click on the deployment options. In my case it is Arduino library.
And at the bottom of the section, press the button Build. A zip file will be automatically downloaded to your computer.
Connect the Arduino GIGA R1 WiFi device to your computer using a USB cable.
Run Inferencing Sketch on the Arduino GIGA R1 WiFiLaunch Arduino IDE. Go to Sketch > Include Library > Add.ZIP Library. Select the.zip file you just downloaded from Edge Impulse and click Open.
In the below code, I added the PDM.setGain(5). This will make the microphone more sensitive to quiet sounds. Also, I replaced the sampleRate(16000) with sampleRate(20000).

Open the Arduino IDE Serial Monitor. Set the baud rate to 115200. If everything goes correctly, you should see the following:
02:38:59.938 -> Recording...
02:39:01.551 -> Recording done
02:39:02.130 -> Predictions (DSP: 26 ms., Classification: 530 ms., Anomaly: 0 ms.):

02:39:06.323 -> speech: 0.10276Here is my demo setup with the Arduino Giga R1.
And, finally here is a demonstration video of what the final result looks like.
This project demonstrated the potential of generative AI, synthetic dataset and edge computing in developing efficient and practical audio classification systems for various applications. By utilizing synthetic data generated through AI, we can overcome limitations of real-world data acquisition, like cost and diversity, and train our model more effectively.
This audio classifier is publicly accessible on Edge Impulse as a project. All the code referenced in this story is available in my github repo. Thank you for reading!
