<h3>Create MD5 checksums (audio samples)</h3>

<p>This will create an MD5 checksum for each group of 48000 audio samples.<br> The number of samples per group can be set arbitrarily, but it's good practice to match the samplerate of the media file (so you will get one checksum per second).</p>
|
||||
<p>Examples for other samplerates:</p>
|
||||
<ul>
|
||||
<li>44.1 kHz: "asetnsamples=n=44100"</li>
|
||||
<li>96 kHz: "asetnsamples=n=96000"</li>
|
||||
</ul>
|
||||
<p>Note: This filter trandscodes audio to 16 bit PCM by default. The generated framemd5s will represent this value. Validating these framemd5s will require using the same default settings.</p>
