I have a bluetooth microphone device with a maximum sampling rate input of 8000hz. I want to use it in a patch set at 44100hz because the sound card don't go under that sampling rate. Is there anyway to convert direct after the adc~ the 8000hz sound to 44100hz?

Are you sure its the sampling rate? I guess its the highest frequency it

will pass on. Does it work? how does it sound in Max?

If your mic works in your operating system, the OS will deal with it, no

need to worry about sample rate conversion...

If your mic would put out 8000 Hz, you would have given it back to the 

If you really want to change 8000 Hz to 44100 Hz, make sure you have a 

sound card with at least 192 kHz sampling rate... ;-)

If your mic would put out 8000 Hz, you would have given it back to the 
dealer or thrown it into the trash....

This answer don't really help. I need technical advice not artistic one ;)

OK if I use the speaker in the headset because the sampling rate stay the same.

I plan to use the noise shield technology in a context of a live performance.

The OS don't deal with the conversion. 
jawbone in = 8000hz sampling rate
mac out = 44100 hz samplig rate

by the way, the link in your signature don't work.

I can't imagine how audio at a rate that isn't the system rate is 

delivered to an application, if the OS doesn't handle it. How is this 

poly~ can upsample, but only by powers of two.

What OS are you on? If you're on the Mac, what does Audio MIDI Setup  
say as far as input rates go?

I can't imagine how audio at a rate that isn't the system rate is  
delivered to an application, if the OS doesn't handle it. How is this  
audio delivered into Max?

Are there drivers for the headset? Then you don't have to deal with it, 

the drivers do it. Do you get the headset configured in Audio/Midisetup?

Max doesn't have any audio drivers, but it talks to any drivers, they 

provide info about sampling rate and alike.

In OS X 10.4.x you can define an aggregat device (multiple interfaces) 

which will have an option of "resample" (You don't want to limit your
