To speed things up, the Stable Audio architecture operates on a heavily simplified, compressed audio representation to reduce inference time (the amount of time it takes for a machine learning model to generate an output once it has been given an input). To train its model, Stability partnered with stock music provider AudioSparx and licensed a data set "consisting of over 800,000 audio files containing music, sound effects, and single-instrument stems, as well as corresponding text metadata." After feeding 19,500 hours of audio into the model, Stable Audio knows how to imitate certain sounds it has heard on command because the sounds have been associated with text descriptions of them within its neural network. On its promotional page, Stability provides examples of the AI model in action with prompts like "epic trailer music intense tribal percussion and brass" and "lofi hip hop beat melodic chillhop 85 bpm." It also offers samples of sound effects generated using Stable Audio, such as an airline pilot speaking over an intercom and people talking in a busy restaurant. Judging by production samples, it seems like a significant audio quality upgrade from previous AI audio generators we've seen. Now Stability and Harmonai want to break into commercial AI audio production with Stable Audio. Not content to limit itself to generating images, the company branched out into audio by backing Harmonai, an AI lab that launched music generator Dance Diffusion in September. If you'll recall, Stability AI is the company that helped fund the creation of Stable Diffusion, a latent diffusion image synthesis model released in August 2022. That’s it! Similarly, you can apply several videos to get one perfect video.Further Reading Hear Elvis sing Baby Got Back using AI-and learn how it was made As soon as you drop the second video, a green outline will be shown on the preview window which will let you decide the screen of second video. Now, drag the second video just below the first one to make sure that you get the picture in picture effect. This should help you in selecting the “base” video.ĭrag the first video from the “Media Library” to the time line. Before you continue, make sure that you will be able to detach the audio track from the one video but the audio track from the second video will not be removed. One video will be the base video and you can also set the size of the second, third or fourth video. Overlaying videos, namely Picture in picture, Filmora Video Editor will let you mix several videos to form one amazing video. Filmora Video Editor isn’t mere a video mixing tool but it will also let you add different audio files with the single video. So, one track will be played for both videos. Apart from that, it also has an exclusive feature called Picture in Picture mode which will let you play a video inside a video, so in the same frame, you will be able to play the both videos without a single problem. With Filmora Video Editor, you can not only join different clips but can also split a single clip into multiple clips and can use specific part of that clip in your video mix.
