Yes,actually I want get the spectrum of the linein in realtime and I achieved it using the exsample.but I want the smaller latency.so I want to use asio to achieved it .

The example shows you how to choose the input driver.
[code:2nhrvtoa]system->getRecordNumDrivers(&numdrivers)

system->recordStart(recorddriver, sound, looping);[/code:2nhrvtoa]

recorddriver is an integer between 0 and numdrivers

you can work out which one is the asio driver by using
[code:2nhrvtoa]system->getRecordDriverInfo(count, name, 256, 0);[/code:2nhrvtoa]

Yes ,I have tested the pitchdetection example,when I choice the outputtype-> ASIO,I can see nothing about the ASIO in the playback and record driver selection and no pitch detected.

so I think maybe there is something wrong with the asio installation.but I can use the asio( asio4all ) in winamp.
How is the correct thing?
If I use the asio,are the steps like below?

record the linein -> play it -> get the spectrum -> again

I tested the "pitchdetection", if I choice the Directsound in output type,I can hear two voices ,but if I choice the asio in output type,I can only hear one voice came from input,so I guess the asio didn’t work .how can I enable the asio function?

Ps:
I set the volume to 100%,so I can hear two sounds.

I have tested the asio driver as below:
asio4all v2
asio2ks
axasio
which is the best one?

the playback driver is :Realtek HD audio output.
