- Description: Hi All, I need standalone C source code to perform a high pass and low pass and band pass filter pcm or wave files. as in
#define PCM_FILE1 "d:\\project\\data\\pcm\\es_00_20.pcm"
#define PCM_FILE2 "d:\\project\\data\\pcm\\es_00.pcm"
The specifications are from amplitude of 0dB, Length of 64. The cutoff for low pass is 350kHz. for high pass the minimum pass through frequency is 300Hz. For bandpass, it is between 300Hz to 3500Hz. I need to be guided through the whole process of setting up the program. (The project used to be done by Nicov completed as a standalone C file with two void functions). This project is urgent and to be done as soon as possible. 1 day is best.Additional Info (Added 1/6/2009 at 21:35 EST)...The payment is in USD or SGD? Singapore dollars I assume.Additional Info (Added 1/6/2009 at 22:31 EST)...C source code to perform a high pass and low pass and band pass filter FOR pcm or wave files. as in
#define PCM_FILE1 "d:\\project\\data\\pcm\\es_00_20.pcm"
Additional Info (Added 1/6/2009 at 23:36 EST)...Please specify what formula and specification you want to use. Can message or email me here.Additional Info (Added 1/7/2009 at 0:11 EST)...Can look here. It's been done before. http://www.scriptlance.com/projects/1093534113.shtml?hl=Hi%20All%2C%20I%20need%20standalone%20C%20source%20code%20to%20perform%20a%20high%20pass%20and%20low%20pass
