Audio Sample Rate - Sample rate defines how many times per second a sound is sampled.Audio Bitrate - Weather you use CBR or VBR, choose the highest bitrate you can afford (at the expense of a bigger file size) for the best audio quality.Use CBR when you want a constant bitrate throughout.

However, VBR may also introduce playback/seek issues due to the variability in bitrate. Choose VBR when you want to optimize file size and quality (the encoder will use a higher bitrate for complex content while saving bitrate from areas that do not need as much data.

YTD has poor download speeds and no batch mechanism in the freemium. It works on all macOS after version 10.6. For security reasons, It has been checked for viruses by VirusTotals and is safe. It also provides a tag editor so you can store your music as you want. Many free converters are unable to download in bulk like YTD, but MediaHuman can do this. MH can export all the downloads to iTunes. Y2Mate, on the other hand, only can be used for YT. You can use it for Dailymotion, Vimeo, SoundCloud, and more. YouTube is not the only website it supports. While the user interface is a bit dated, it is easy to use as the main screen carries much of what you need to download and convert videos. Most other audio converters are based out of a website, like YTD, but MediaHuman (MH) sticks to a downloadable format. MediaHuman has kept their converter in great shape throughout the years.
