This is the essential tutorial needed to get up to speed with Pro Tools, while learning a few new things about digital audio and recording along the way.

Recently I found many poeple want to get a converter to mp4 or mp3 to convert videos from YouTube.com,

MP3 - is an acronym for MPEG-1 (or MPEG-2) Layer 3 audio encoding (it is not an acronym for MPEG-3). MP3 is a popular compression format used for audio files on computers and portable devices.

MP4 - is a new container format, a container format allows you to combine different multimedia streams into one single file. Multimedia containers are for example the well known AVI, MPEG , Matroska, OGM. MP4 is the global file extension for the official container format defined in the MPEG-4 standard. MP4 is streamable and supports all kinds of multimedia content, multiple audio-, video-, subtitlestreams, pictures, variable-framerates, -bitrates, -samplerates...) and advanced content like 2D and 3D animated graphics, user interactivity, DVD-like menus.

I am so excited that I found something about conversion, a step-by-step guide .
You will understand how to make it here.
