looks like the AsioOut you create is always for the default device. Use the constructor that takes a driver name or driver index.

Hi, I am drawing the waveform of a wav file on a mediaobject representation. The user can make the duration of this media object smaller. The wav is then played only the duration and the rest is cut...

I would suggest using Mp3FileReader (or NLayer) to decode the file. Once you have the raw PCM samples, you'll need to do voice analysis. I'm not familiar with the state of the art there, but there's...

You can't change the length of a WaveStream. I'd probably create a wrapper WaveStream with a shorter duration, whose Read method passes into the full WaveFileReader, but doesn't read more than the...

Does it actually benefit from the conversion? I am still learning about bit depth and digital audio in general, but if the loopback records the buffer at 8 bit and you convert it to 16 bit doesn't that...
View ArticleNew Post: Adding 16 Bit Stereo , Conversion in WasapiLoopback.
Not sure where you got 8 bit from. WasapiLoopBack is in Float, 32 Bit. And no inbuilt conversion is available. And as for most applications, you probably don´t want Float, and 16 bit, or 24 bit. So...

Ah, for some reason I was under the impression WasapiLoopBack recorded at 8 bit. Thanks for clearing that up. Just out of curiosity though if you did convert an 8 bit file to 16 bit, would there be any...

No worries, it´s always good to ask, i do it all the time:) And no, Quality is always determined by it´s weakest link. Meaning, if it´s 8 bit, it will always have that quality no matter what. Same with...

I am trying to get the Asio output to playback through the waveProvider. It looks like waveProvider needs a byte array of 16 bit samples, but ASIO output is a 32 bit float array. How can I go about...

WaveProvider can be any format. So why not just play back audio at 32 bit float? You can use WaveFloatTo16Provider to get to 16 bit from float as well if you want

I guess it sends some ID3v2 tags through. The ACM error is likely down to destination buffer not big enough. See how many input bytes are being passed into AcmStream.Convert, and what size destination...
