Hi, I need to do some basic and non basic DSP programming in C#. At its core, it includes the generation of a sin wave deciding its frequency in Hertz. Then I'd like to Frequency Modulate it and maybe filter it. Can you suggest any library to help me? Ideally this should also work in a SilverLight environment, as my aim is to showcase a...
I am interested in finding out if there exists a program or library which can perform the following task, and would be suitable for running as part of a server side process on a web site. (it's okay if it takes longer than the 200 milisecond maximum that is reasonable for a single page request-I can run it as an asynchronous process) Th...

I'm trying to make a pyaudio input stream but can't figure out how to make it. What I did is: a = pyaudio.PyAudio() Then tried to call a.open() but I don't know the arguments I should type in. It asks me to check Stream.init for a reference, but I don't know what a PA_MANAGER is and the documentation isn't useful at all about it. ...

Hi community, I'm a bit confused. Is there any simple way to set proper audio devices (in/out) in my VoIP .NET application w/o using of DirectX?

I've always been curious about audio conversion software, but I have never seen a proper explanation from a beginners point of view as to how to write a simple program that converts for example, a mp3 file to a wav. I'm not asking about any of the complex algorithms involved, just a small example using a simple library. Searching on SO, ...

How hard is it to do that? Someone told me that it's incredible hard playing audio on the iPhone. Can't really believe it. But he said playing one is hard, but playing two or three at same time is incredible hard. Sounded scary. What can you guys say about this? What I want to do: I have about 10 CAF files with little blips and beeps an...

I have 2 audio files for primary and background music that I want to merge (not concatenate). The final audio file should be as long as the primary file, and if the background music is shorter then it should repeat. If there a Linux command or a Python library that can be used to do this? Sox supports merging, but does not appear to all...
Hi I'm working currently on a small microhpone, connected to PC via an FPGA. The FPGA spits a raw datastream via UART/USB into my computer. I'm able to record, play and analyze the data. But I can't play the "live" audiostream directly. What works is saving the datastream in PCM raw-format with a custom made C-program, and piping the ...

OK. If one uses the System Sounds Services for iPhone sound effects, there is no way to alter the level of the resulting sounds programmatically. Even worse, if one reduces the volume using the ringer volume control on the side of the iPhone to a very low level, then starts the app, the sound effects will be inaudible. On the other hand,...
There are several different audio libraries, however, none of them meet my exact needs: - It needs to be cross-platform. - It needs to be able to use the ALSA, PulseAudio or any other common default mixer under Linux. - It needs to be able to autodetect the sample frequency. - It needs to be (fairly) simple in usage, if instead someone c...
