i think most of those sites have to be payed for , its not worth the money ,i think audio mack is free ,, but i dont even know how to do it, maybe guitar band on my computer have not done for years
i use a camera with a video recording option (GoPro), and transfer the video file to my laptop and use the software to export it to an audio file, and then upload the audio file to sound cloud web site (free) and copy the link in sound cloud to this website.
So the sound quality is very poor, but for me it’s an easy option where you can just record instantly.
