Interpolating delay lines in MSP

February 28, 2008 | 6:30 pm

Hi,

I’m looking for an MSP external to delay a signal by fractional sample amounts. Delay~ and Tapin/Tapout~ sort of do the job, but they use linear interpolation between samples that causes considerable high frequency loss. I’m hoping to find an MSP delayline that uses all-pass interpolation instead (this gives better high frequency response). Is anyone aware of one?

I came across flextdelay~ over at Max Objects.com, but it’s poorly documented and I can’t get it to run. http://www.maxobjects.com/?request=delay+allpass+interp&operateur=AND&id_plateforme=0&Submit=OK

I’m on an intel mac.

Any ideas?

Best,

Dave

You could use rtcmix~ ( http://rtcmix.org/rtcmix~ ) or csound~
( http://www.davixology.com/csound~.html ), but those are both
‘external’ languages. Both have a number of different types of delay
units in them.
