CleanBeats.ai

Clean Beats is a github repo that, given an audio file and a transcript will automatically dub out all the explitives in the given audio file and return said file for download.

We finished that functionality the first night of the hackathon. Then, we decided, what if we were able to, instead of dubbing out the word, replace the word with any other word: essentially creating a "find and replace" program for audio files.

However, we were primarily using songs as our test files: imagine jamming Siri's voice into the middle of an Eminem Song. It wouldn't work.

So our challenge for the rest of the weekend was essentially to build a model that could automatically run style transfer on audio files seeded with a text to speech generated audio and the context surrounding the word. In the proccess, we build a data pipeline so that every time somebody uses our "Clean Beats" website functionality, we build up our dataset for our style transfer/generator network.

Our Data Pipeline

Long Term Applications

At this point, the sun was starting to rise, and we were almost out of time. We were able to train a generator that demonstrated our proof of concept that our generator was able to learn the content to some extent.

We hope to improve the performance of our generator/style transfer network to allow replacement audio to be almost indistinguishable from its context. Applications of our generator could include live stream audio replacement or post production editing of long audio files
