'Trim a section' when encoding mp3 with lame?

[scooter41]

Hi there,

 

I often use LAME with a php script to dynamically compress 320k mp3's for an online store, and make 96k preview mp3's.

 

However the client now wants to take a 'portion' of that track to play as a preview only.

 

I use the following command to dynamically convert the whole track, however is it possible to specify start and end times perhaps so I can just trim the middle portion of the track?

 

$encode_cmd = "/usr/bin/lame/bin/lame -b 96 --resample 44.1 $origFile $convFile";

$output = exec($encode_cmd . ' 2>&1', $output, $return);

 

Thanks for any help in advance!!

I'm not sure that you can do that with LAME, have you read the man pages? If not, take a look into sox, I think that has a higher level of control when manipulating audio files.

I have used MP3Gain for something similar.

what if you stream the full length into the player but stop the stream at a certain point creating your "smaller" section.

 

Don't know exactly how to do it but it sounds reasonable
