Using Sound card Creative Audigy 4 pro for multiple microphone input

Started by salrome April 23, 2007
 Hi
My goal is to take sound data from multiple microphones into MATLAB
workspace.

I have got the sound card Creative Audigy 4 pro for multiple microphone
input.I would be glad if some one has info regarding

1.How to connect multiple microphones to this card,which terminals/ports
will be
used.
2.How can I read the audio data from the microphones through the sound
card in MATLAB(for example using MATLAB data acquisition tool box
3-which additional equipment will be required for getting data into
computer


Best Regards
salrome

Asking the same question several times won't change the facts: You are under-equipped for your task, both with hardware and with knowledge. Get somebody who has a clue about audio to setup a computer for you. Regards, Andor

Audigy 4 Pro is maybe not the most suitable for this task there. Why, because of, w/o using ASIO device drivers, it's not possible to enable more than one input source at a time w/o all being mixed into one stereo stream (using "What U Hear" recording mode). Does MatLab support ASIO? There are in Audigy 4 Pro PCI card, - two analog mono line-inputs (Aux-In) and one S/PDIF input (internal connectors) Extarnal IO/ Hub - one Optical S/PDIF I/O - Line-In 1/Mic In 1 (two mono or one stereo line sources or one mono mic) - Line-In 2 (two mono or one stereo) - Line-In 3 (two mono or one stereo) - one Coaxial S/PDIG I/O so, in theory, you have - one mono (pre-amplified) input port for microphone - max 8 analog mono and 2-3 S/PDIF inputs to use for michrophones, if you have external mic pre-amp w/ as many outputs (as analog and/or digital) or you're using powered microphones I can't say sure if all these channels can be enabled simultaenously in Audigy mixer or defined in MatLab as separate sources. How many microphones you would be using (max)? There are some 'standalone' analog mic-preamps w/ 8 I/Os you could add into your Audigy 4 Pro system as like the SM Pro Audio PR8 8-Channel Microphone Preamp (~$100) - http://www.smproaudio.com/PR8.htm Some more listed @ http://www.zzounds.com/cat--Microphone-Preamps--2891 jtp _____________________________________ Do you know a company who employs DSP engineers?

NOTE: Above addon is usable for you only if the software you're using for recording through Audigy 4 Pro supports ASIO device driver mode !!! jtp _____________________________________ Do you know a company who employs DSP engineers? Is it already listed at http://dsprelated.com/employers.php ?

Thanks you very much jtp! Initially,I want to work on only two microphones. Best Regards Salrome _____________________________________ Do you know a company who employs DSP engineers? Is it already listed at http://dsprelated.com/employers.php ?

In this case, Audigy 4 can be used w/o mentioned mic-pre addon if you just connect - two (battery) powered mono microphones conneceted through one of those available stereo Line -input ports. For this connection, you need a cable/adapter to get two mono channels feeded through one mini jack connector or - if you can use ASIO drivers in MatLab, then only the 2nd microphone needs to be (battery) powered But, if you need to use quality microphones/connections in your measures then aditional mic-preamp is a must. jtp _____________________________________ Do you know a company who employs DSP engineers?

Have you looked on Audigy's web site for a manual?

The sound card will save the microphone data as one or more files. How to read them with Matlab is in the Matlab manual. Jerry -- Engineering is the art of making what you want from things you can get. ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
