You can convert spectrograms to make your job easier. Using both of them, you can easily create a model that can distinguish specific audio signals from one another. The former is a collection of audio clips of people reading books without any background noise, whereas the latter is a collection of background noises. To work on this project, you can use the LibriSpeech and the UrbanNoise8k datasets. You can use deep learning to perform this as well! In that instance, you’re separating the lyrics’ audio signals from the rest of the music. A rough example of audio source separation in real-life is when you distinguish the lyrics of a song. You perform audio source separation every day. In simple terms, audio source separation focuses on distinguishing different types of audio source signals present in the midst of signals. Separate Audio SourcesĪnother prevalent topic among speech processing projects is the separation of audio sources.

While some people use software solutions to eliminate background noise, you can try representing audio in a different format and remove the unnecessary clutter from your file. Shazam is an app that lets people identify songs by listening through a small section of the same.Ī common problem in generating audio fingerprints is background noise. Shazam is probably the most famous example of an audio fingerprinting application. They have the name ‘fingerprint’ in them because every audio fingerprint is unique, just like human fingerprints.īy generating audio fingerprints, you can identify the source of a particular sound at any instance. You can say that an audio fingerprint is a summary of a particular audio signal. When you generate an audio signal by extracting the relevant acoustic features from a piece of audio, then condense the specific audio signal, we call this process audio fingerprinting. One of the most recent and impressive technologies is audio fingerprinting, that’s why we’ve added it in our list of speech processing projects. You might also use slowing down or speeding up of sound to suit the needs of your model. Additionally, we recommend using a convolutional neural network, also known as CNN, to perform audio classification. Use Data Augmentation to avoid overfitting, which would bother you a lot while performing audio classification. You can use small audio clips to train the neural network. Īs a beginner, focus on extracting specific features from an audio file and analyzing it through a neural network. There are currently 632 audio event classes and more than two million sound clips present in AudioSet. They are correctly labeled, so working with them is relatively more straightforward. You can use the audio files present in AudioSet to train and test your model. They all are 10-seconds long and are incredibly varied. AudioSet is a vast collection of labeled audio that they collected from YouTube videos. You might wonder how you’d start working on an audio classification project, but don’t worry because Google has got your back through AudioSet. So, you can work on an audio classification project and get ahead of your peers with ease.
