Dear members,

I need a way to use directshow to be able to get audio recorded as
buffers
(like in real-time encoding of PCM buffers into mp3 buffers)

I found DSPack for delphi , but didn't know how to record audio as PCM
buffers

any help would be appreciated

thanx in advance

Hi,
There are many ways of doing this. The most common is writing your
DirectShow Inplace filter that will pass the data downstream, giving
you access to the audio data. If you need this PCM to be written in
mp3 you'll need MP3 audio encoder.
