Are there any good AI websites for creating / editing sound files and short music videos?

Can anyone recommend good free AI websites that can do any of the following:

  1. Take a sound file or Youtube video of e.g. a choir singing and remove things like a BUMP or a sound of someone in the audience coughing or sneezing or a baby crying or static?

  2. Take a sound file or Youtube video of a band playing and generally improve the sound quality, to make it more saturated, etc. (E.g. something filmed on a Nokia phone circa 2008)?

  3. Change the accent of a singer or singers in a video?

  4. Take an audio file where someone in a band blew a wrong note and correct it by improving the harmonization in that part of the soundtrack (or re-generate the whole piece as a digital recording with all the right notes)?

  5. Actually create a short video according to your prompts, of an AI person playing a song? For example imagine this hypothetical imput / prompt: “Create me an image of a teenage boy wearing a white Elvis suit singing Always on My Mind on a stage to the accompaniment of a piano, with a middle-aged pianist playing the piano beside him?”

I tried to create a video of a different propt in Invideo, which ChatGPT directed me to, but it required 60 credits to proceed. Before I pay for any of the above, I would like to know if there are any free options that work?

I’m not an AI person, but several of your requirements can be easily handled by splitting the audio track and then using a digital audio app (or a DAW) to process the audio separately. Audacity, for example, can use several auto-tune VST plug-ins, as well as filtering noise, improving dynamics, and removing the odd “bump.” It requires a bit of experience to use them, but there are many free ways to accomplish what you want. You can then combine the audio file back with the video. It’s what I would do.
