New Post: Release build of NAudio 1.5
Hi Mark, I can switch to 1.6 also. I just didn't know that 1.6 is a release-build. Thanks a lot! Kay

Hi James, I was able to modify the equalizer settings (BassTreble only using the Audacity effect as a baseline) while audio was playing. I was using the NAudio library and the bufferedWaveProvider...

I am already writing my own little audio libary to learn more about that topic. I am currently using it for my directsound wrapper. It works perfectly but you need to write a little postcompiler using...

hi Markus, no there is no active development on the mixer API at the moment. It was one of the first bits of NAudio I did, back when I didn't have a clue about how to do P/Invoke, and hasn't turned out...

I'd do this with a custom ISampleProvider, which would make it easy to multiply the samples by different left and right channel volumes as they came through. Look at the source code for...

I can set master volume for overall song. like: volumesampleprovider class: public class VolumeSampleProvider : ISampleProvider { private ISampleProvider source; private float volume; public...

I am working with a speed drummer, and need to detect each beat of a single drum. How would I do this using NAudio?

Thanks Paul, that looks like the way to tackle it. Will be some modification to the way the WaveStream is handled. I'm glad that we have Mark's mp3 streaming demo ! Jim

Hi James, Is there a way I could take a peek at the code. I am tasked to make a 27-band equalizer (similar to Audacity) and looking at a 10-band may help me along the way. We can take this offline if...

If you are making effects for NAudio, then I strongly recommend using ISampleProvider as your base class rather than WaveStream. It will make your life much simpler. I'm hoping to get some example...

Thanks Mark for the tip. Also I will take this opportunity to thank you for a great piece of work :) brunp - I'm happy to post some code up and how I tackled it a bit later. The codes in a bit of a...

Ahh interesting.. I will experiment with all options. I am using this with XNA for a game prototype. I am using XNA's default audio library to handle UI and game sounds, but I needed something else to...

Followed the WPF example and still have the same issue. I used the NAudio WPF example SampleAggrigator rather than my own. Although, I stripped out the volume code; didn't need it. The spectrum...

OK, what is likely happening is that your soundcard is using large buffers. So when a new buffer is filled up it reads enough from the source to do several FFTs. Your options are either to work with...

works pretty good! There is a little bit of a clipping noise when increasing volume but its not bad. One thing I noticed (or maybe its my ears) is that past a volume of 5 there seems to be no...

the difference between 5x and 10x should be 6dB, which is the same as the difference between 1x and 2x. However, by the time you've amplified that much, clipping may be reducing any further gains. A...

Ok cool, that explains it. Since really this is being used as my BackGroundMusic player... I will create a proper ratio of volume values between 0 and 5 simulated visually as 0-9, and use the last...

I want the same buffer size across all devices no matter what the soundcard supports. What buffer size do you recommend? Where do I change it? 32ms refresh is not a necessity. It was the refresh rate I...

Just use the code I showed above, and add a LeftVolume and RightVolume property instead of the Volume one.

How about if I figure out frames per second, grab the current frame every ~40ms (needs to be a rate that is invisible to the human eye when I render) and run an FFT on that instead of relying on the...
