        <div><div class="section"><p>For maximum flexibility, perform all

editing in Adobe Sound (.asnd) format. If you primarily use Soundbooth

with Adobe Flash, Premiere Pro, and After Effects, use ASND format

exclusively. When you want to share files with a broader range of applications,

such as disc-burning utilities, save to the WAV or AIF formats.

Save to the compressed mp3 and AAC formats only when creating files

for the web or portable media players.</p>

<p>Here are details about

each audio format:</p>

</div>

<div class="section"><h4 class="sectiontitle">Adobe Sound (.asnd)</h4><p>ASND format lets you readjust fades

and effects, and store history snapshots that restore previous edits.

This format also supports multitrack mixes, which let you combine

multiple audio files and scores. Adobe Flash, Premiere Pro, and

After Effects import ASND files, tightly integrating those applications

with Soundbooth.</p>

</div>

<div class="section"><h4 class="sectiontitle">Advanced Audio Coding (.aac)</h4><p>AAC is a compressed format based on

MPEG-4. The alternative filename extension .m4a appears in many

applications, including Apple iTunes. At similar bit rates, this

format achieves higher audio quality than mp3 format.</p>

</div>

<div class="section"><h4 class="sectiontitle">Audio Interchange File Format (.aif)</h4><p>AIF

is the standard, uncompressed audio file format for Mac&#160;OS.</p>

</div>

<div class="section"><h4 class="sectiontitle">mp3 Audio (.mp3)</h4><p>mp3 is the most widely used format for web‑based

audio and portable media players. This format highly compresses

file size, optimizing audio for fast downloads. The compression

process, however, slightly reduces quality and introduces artifacts,

particularly in quiet passages.</p>

<div class="tip"><img src="images/tip_help.png" />If you edit

an mp3 file, avoid saving it to the same format. Resaving in mp3 format

recompresses data, lowering audio quality.</div></div>

<div class="section"><h4 class="sectiontitle">Windows Waveform (.wav)</h4><p>Windows

Waveform is the standard, uncompressed audio format for the Windows

operating system.</p>
