|
<h2 id="description">Description</h2>
|
|
<p>Extracts the audio track from a video file and saves it as a standalone audio file, preserving quality and format.<br />
|
|
Useful for sound design, transcription workflows, remixing, archival storage, or preparing audio-only deliverables.</p>
|
|
|
|
<h2 id="purpose">Purpose</h2>
|
|
<p><code class="language-plaintext highlighter-rouge">extract_sound</code> allows creators to quickly isolate the audio component of any media file.<br />
|
|
This is ideal for:</p>
|
|
<ul>
|
|
<li>podcasts derived from video interviews,</li>
|
|
<li>music extraction for editing or remixing,</li>
|
|
<li>voice-over capture,</li>
|
|
<li>archival audio preparation,</li>
|
|
<li>preprocessing audio for tools like transcription or captioning.</li>
|
|
</ul>
|
|
|
|
<h2 id="how-it-works">How It Works</h2>
|
|
<ol>
|
|
<li><strong>Stream Selection</strong><br />
|
|
The tool identifies the primary audio stream from the input file.</li>
|
|
<li><strong>Direct Copy or Re-encode</strong><br />
|
|
Depending on videobeaux global flags, audio is either:
|
|
<ul>
|
|
<li>copied without re-encoding for perfect fidelity, or</li>
|
|
<li>encoded with the user-specified audio codec and bitrate.</li>
|
|
</ul>
|
|
</li>
|
|
<li><strong>Output Rendering</strong><br />
|
|
The extracted audio is written to the output file specified with <code class="language-plaintext highlighter-rouge">-o</code>.</li>
|
|
<li><strong>No Video Processing</strong><br />
|
|
Video streams are ignored; only the audio track is saved.</li>
|
|
</ol>

<h2 id="program-template">Program Template</h2>
|

<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>videobeaux -P extract_sound \
|
|
-i input.mp4 \
|
|
-o output.mp4
|
|
</code></pre></div></div>
|
|
|
|
<h2 id="arguments">Arguments</h2>
|
|
<ul>
|
|
<li><em>(No program-specific arguments — this tool relies entirely on global videobeaux audio settings such as codec, bitrate, and container format.)</em></li>
|
|
</ul>
|
|
|
|
<h2 id="real-world-example">Real World Example</h2>
|
|
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>videobeaux -P extract_sound \
|
|
-i myvideo.mp4 \
|
|
-o extract_sound_styled.mp4
|
|
</code></pre></div></div>
|
|
|
|
<h2 id="technical-notes">Technical Notes</h2>
|
|
<ul>
|
|
<li>The output file extension determines the final audio container (e.g., <code class="language-plaintext highlighter-rouge">.mp3</code>, <code class="language-plaintext highlighter-rouge">.wav</code>, <code class="language-plaintext highlighter-rouge">.aac</code>).</li>
|
|
<li>If no re-encode options are given, videobeaux may default to stream copy.</li>
|
|
<li>Multi-track audio is not mixed—typically the first audio stream is extracted unless overridden globally.</li>
|
|
<li>Useful for batch pipelines when paired with folder recursion or metadata extraction.</li>
|
|
</ul>
|
|
|
|
<h2 id="recommended-usage">Recommended Usage</h2>
|
|
<ul>
|
|
<li>Extracting dialogue or interviews for transcription.</li>
|
|
<li>Creating podcast audio from filmed sessions.</li>
|
|
<li>Pulling music or SFX layers from video renders.</li>
|
|
<li>Archival workflows where audio must be stored separately.</li>
|
|
</ul>
|
|
|
|
<h2 id="quality-tips">Quality Tips</h2>
|
|
<ul>
|
|
<li>Use <code class="language-plaintext highlighter-rouge">.wav</code> for lossless extraction.</li>
|
|
<li>Use <code class="language-plaintext highlighter-rouge">.aac</code> or <code class="language-plaintext highlighter-rouge">.mp3</code> for lightweight distribution formats.</li>
|
|
<li>If audio is distorted or clipped, normalize or limit in a separate audio-processing step.</li>
|
|
<li>When exporting from mixed sources, ensure consistent bitrate settings to avoid quality mismatches.</li>
|
|
</ul>
