WAV is a container format, doesn't tell you anything about the contents. Perhaps we should refer to LPCM on the one hand, and compressed digital on the other. -- Stewart Pinkerton | Music is Art -

Hi, What I try to do: Type of audio: Solo Vocal music. Samlingrate : 44100 Desired Output : Pitch (frequency), hopefully > =10 detections per second. I've read a lot of discussions on this subject on the forum. As you will probably see in my post, my knowledge in maths are limited. I work as a software developer, but mainly GUI/DB. I started out creating an algorithm without doing much

Hello, I'm Seb and I have a little problem I would like to submit to you. At the time of an acquisition of an impulse response of a room (room of music, canteen or another thing), it is possible that this answer is disturbed because of the noise (a car which passes, a person who speaks etc). Thus the nature of the noise is not known. It would thus be necessary, from various acquisitio...

I am using pure data. I am using -- kick, snare, hats to create a simple beat with a bassline. But for some reason, each instrument does _not_ sound the like the one i listen in, say dnb music. I have added reverb to each instrument but still there is no change. They sound too hollow and artificial. From what I can gather, I should be using a 1) EQ filter 2) A constant ambient b...

Maybe I have too much time on my hands.... Anyway, I've been researching on the web for methods useful in generating cell phone ring tones. What I want to do is generate a monotone ring tone.

What I haven't been able to do is get MidNotate to save a single instru...

Hi everyone. I was greatly interested in a thread a short while ago on performing music-orientated audio synthesis in the frequency domain. Initially I was confused about the low frequency accuracy of the resynthesis. E.g. to keep the latency down to 1/50th of a second you'd need a window size of 1/100th of a second. For the purpose of argument, assume that I'm going to synthesise a sing...

I have a WAV file which is a complex audio signal generated in PC music software. I would like to play it back at an increased speed of 100 times the original. For example, if the dominant frequency was 20KHz, the upper limit of audio, at playback it would be 2MHz. That is as high as I need to go. Obviously, this cannot be done, or output, from the PC alone. I assume some type of program...

Hi: Eliminate all vocalizations, kicks, spikes, clicks, snares, hiss, saxophones, leads and similar instruments by recognizing their waveforms rather than removing the central channel of a recording. Current "voice cancellers" work by ridding whatever is identical in both right and left. This would not eliminate vocals if they were recorded differently in the right and left channels. I d...

The church I belong to is planning a website which will include recorded sermons. The proposal for site design and hosting did not explicitly mention how much online storage was included.
