2. In This Chapter, you’ll learn on:
Identify audio processing software
Utilising audio editing software to edit audio
Compress audio file using appropriate software
3. A digital audio editor is a computer
application for audio editing, i.e.
manipulating digital audio.
Digital audio editors are the main software
component of a digital audio workstation.
4. For use with Music
Editors designed for use with music typically allow
the user to do the following:
Record audio from one or more inputs and store
recordings in the computer's memory as digital
audio
Edit the start time, stop time, and duration of any
sound on the audio timeline
Fade into or out of a clip (e.g. an S-fade out during
applause after a performance), or between clips
(e.g. crossfading between takes)
5. For use with Music
Mix multiple sound sources/tracks, combine them at various
volume levels and pan from channel to channel to one or
more output tracks
Apply simple or advanced effects or filters,
including compression, expansion, flanging, reverb, audio noise
reduction and equalization to change the audio
Playback sound (often after being mixed) that can be sent to
one or more outputs, such as speakers, additional processors, or
a recording medium
Conversion between different audio file formats, or between
different sound quality levels
Typically these tasks can be performed in a manner that is both
non-linear and non-destructive.
6. Compressing Audio Files
An audio file, such as a WAV (Windows Audio Video)
format, can store up to 10 MB per minute, and this
equates to a sizable digital file. It is not uncommon to
give in to the natural tendency to keep right on
recording until the bytes run out. Well, you can have
your sound-filled byte pie and hear it too. Enjoy the
sounds that fill the some of the space of the hard
disk by getting rid of the extra audio weight and the
guilt that goes with it. Learn how to compress audio
files that fatten up the computer and still have room
for additional data.
7. How to Convert & Compress WMA Files Into MP3 Files
By converting WMA files into MP3 files you can further
compress the audio files' data. In most cases, MP3
files have a bit rate of 128 kbps, which makes their
audio quality comparable to that of other formats.
By choosing a lower bit rate than 128 kbps when
converting a WMA file into a MP3 file, you can further
compress the WMA file. This process can be done
using any free audio converter such as Switch or
dBpoweramp.
