Thanks Mark, setting that to False and setting the Latency to 2 stops it from using excessive CPU :)

Great. I've checked in a fix at GitHub that hopefully will resolve the high CPU issue in event mode

are you calling Stop after disposing WaveOut?

sounds like a format issue. Can you recognize your voice at all? What happens if you just record at the default WasapiCapture wave format (i.e. don't set it explicitly)?

New Post: Changing frequency/pitchshifting
NAudio does not include a pitch shifting algorithm directly, but it does give you direct access to the samples so you can implement a pitch shifting algorithm yourself. One I use quite often is SuperPitch. You can see an example of using that here

Thanks for the response Mark, appreciate it.
Am I ok to use that code, or a derivative of it, in a commercial application?

New Post: Changing frequency/pitchshifting
well it originally came from an open source effect in REAPER. I think you are OK, but I can't say for sure since I just ported it. Another alternative I've used in the past is to wrap the soundtouch library, but I've yet to get round to open sourcing my work on that front.

WasapiOut already resamples for you (as does WaveOutEvent), so there is no need for all this code.↧

New Post: Mute Left Or Right Channel While Playing Audio
I'd usually do this by creating an
ISampleProvider implementation similar to VolumeSampleProvider but with separate left/right multipliers. Hopefully I can add something like this to NAudio soon.↧

I'm afraid I cannot help you with this problem as it relates to a separate library. The Dll not found exception should be a clue though. If you don't have that DLL in your path, you won;t be able to use LameMp3FileWriter.

Hi!.
Probably that was the case... i figured out some hours later, sorry.

New Post: Glitch (click noise) on Stop() or Dispose().
Hi.
I found that every time i call Stop() or Dispose() i can hear a noticeable click. As the glitch happens right there, i can't do a FadeIn or FadeOut to solve the little artifacts of the stop or play. I've tried with WaveOut, Wasapi, and DirectSound.
A very simple player:
I thought it was only my system, but the app on other computers does the same.
Thank you.

waveOut = new WaveOut();
waveOut.DeviceNumber = 0;
waveOut.NumberOfBuffers = 2;
waveOut.DesiredLatency = 150;
waveOut.Init(reader)
waveOut.Play()I thought it was only my system, but the app on other computers does the same.
Thank you.

Yes, abruptly stopping audio will often cause a click. To get rid of this, begin a fade-out instead of stopping. Then, once the fadeout has completed, call stop.

I'm afraid I have no knowledge at all of the .spx file format. I'd recommend asking over at the NSpeex project for help.

Ok thanks. About our discussion of the *.flac format and the rumors for windows 10 flac support I found this interesting site:

New Post: AudioMeterInformation PeakValues problem
Hi all,
I'm having a strange problem where the PeakValues are only being populated when the windows sound properties are open and the recording tab is selected. If either of these conditions aren't met, the values just don't update.
I'm using a timer (1ms) to poll AudioMeterInformation.PeakValues as such:
Thanks, Dave

New Post: MIDI File Read Note Length?
1:1:0 0 NoteOn Ch: 1 C6 Vel:87 Len: 167
1:1:240 240 NoteOn Ch: 1 C6 Vel:69 Len: 199
I was able to read the above raw MIDI using nAudio in my C# program. I don't understand what "Len" means however. If that is the NoteLength property, does that mean the first note is played for 167 microseconds? Does that mean it is some tempo value divided by 167? Does it mean that it is played for 240 microseconds since the next note has a "240" as its marker?
I am trying to understand how to calculate NoteLength so I can feed data to another program that works in quarter notes, with other note lengths being a multiple or divisor of a quarter.
Thanks.
