Must-know Tips for Advanced Users

You might know that there exist two types of audio records: lossless and lossy ones. Lossless data typically come in FLAC, AIFF and WAV formats. These are the audio registers compressed in a way to provide the best audio quality possible. They sound like original music records from the studio. Nonetheless, they are extremely large in width. One lossless track may take up to 100 Mb or even more. It’s OK if you have a lot of space on a hard drive and working with music data is your profession. For an amateur listener keeping music in lossless formats might be rather awkward. Not simply lossless moves take a lot of room, but you also need special media players to enjoy or revise the carols. That’s why most people prefer to keep their music collection in a standard lossy MP3 format. Yes, you won’t get all possible details of the song but let’s be honest: few of us have this expensive stereo system at home that fixes you enjoy every single note of the track.

So, the first acces you can follow to compress your audio is to change it from lossless to lossy. There are a lot tools and online services that you may use for it. We will talk about them and their pros and cons later.

The 2nd channel is to reduce the bitrate of a way. If you don’t know, a bitrate determines the quality of the music line. The higher the bitrate, the very best the way announces. For MP3, the best bitrate is 320 kbps. The bitrate can be constant( CBR) that is the same during the course of its part way; and variable( VBR) that increases for strident music divisions or increases for speechles or quieter ones. Registers encoded with VBR are smaller in width likening to the same data with CBR. However , not all media participates and portable designs can playback such a track.

To cut a long story short, you can use two methods to compress audio 😛 TAGEND

Change the record from lossless to lossy; Change the bitrate of the enter.

Those were appropriate tools that we used for our exam. Which one to choose then? Well, it depends on several factors 😛 TAGEND
