advanced audio plugins for avisynth?
 

Shodan,

Is there any support for, or any plans in the future to support more advanced audio plugins for avisynth. I ask becuase TV Captures could always do with some Extra Bass and Tone so an Equalizer plugin would be lovely. I own lots of DirectX plugins for audio (i do lots of music recording), is there a plugin that can load these in?

Edit -

Also, I do a lot of TV Capturing using MJpeg codec. Previously i captured to YUY2. Using Avisynth 2.5, what is the best colorspace for me to capture to? Would i be better off capturing to RGB instead and then converting to YV12? When you then convert to mpeg using TMpeg, what color space do you need to be in then?

Sorry to hit you with loads of questions.

Regards,

James

Have a look at BEFA. Documentation is japanse, but it seems like it does what you need.

Befa( int freq, int sec, int dftsize, int bandwidth, int fade, bool window )


MJPEG is actually YV12, but I haven't found a good codec for it yet. Morgan MJPEG seems good, but it has a very stupid FieldDoubling bug in YV12 mode, besides swapped UV channels. I have written Morgan about the problem, but with no response. :(

Anyway, since I also use MJPEG for transfers, I use:

Avisource("file.avi",pixel_type="yuy2")
or
DirectShowSource("file.avi")

AviSource produces YUY2 input, and DSS produces YV12. In either case it is a good idea to end your script with converttorgb24().

Many thanks shodan.

I've downloaded Befa but i can't work out how to boost a frequency, only cut one. Do you have any idea how to do this with this filter?
