            Seperating two audio channels on Android by Stereo recording
            Asked 2021-Dec-22 at 12:37

            I am trying to record an audio using AudioRecord on android and seperate the right and left channel recordings into two different files and then convert it to wav to be able to play on the phone.But the recorded files have fast speed and it has high pitch.

            I read all the samples and wrote this code but I am not sure which part is causing the problem.

            This is my AudioRecord definition.

            In the WAV-header you have 2 channels (stereo) output format:

            writeShort(output, (short) 2); // number of channels

            If so, then byterate should be 48000 * 4 (= 2 bytes per channel * 2 channels per sample) also the block alignment should be 4 for the same reason.

            Also, you need to write each sample twice, because your output is stereo: once for each channel. E.g.:

            Audio recording in Python with Pyaudio, error ||PaMacCore (AUHAL)|| ... msg=Audio Unit: cannot do in current context
            Asked 2021-Nov-09 at 04:30

            I am using pyaudio to record sounds on my Mac BigSur 11.6 (20G165). Specifically, I'm redirecting sound from an application to the input using BlackHole, which works fine.

            It usually works fine but, sometimes, I get this error in the Terminal:

            ||PaMacCore (AUHAL)|| Error on line 2500: err='-10863', msg=Audio Unit: cannot do in current context

            Any idea why or how I could prevent it from happening (like, waiting until PaMacCore is ready to record again or something)?

            Apparently the problem were mismatched bitrates in BlackHole's aggregated output device. I was aggregating Blackhole's output (44,1kHz) and the Mac Speakers (48kHz). This did not cause any consistent bad behaviour but sometimes led to these errors.

            Xaudio2 crashes if I exit application while sound is playing
            Asked 2021-Mar-17 at 09:05

            I have been tying to setup xaudio2 and while I thought I succeeded, I quit the application while the sound is still playing and the program crashed. originally I made it so that when receiving a WM_CLOSE message I would make sure that the source voices had stopped. this drastically reduced the number of crashes, but still around 1/5 times I exit the application the program crashes. this is what it says "Exception thrown at 0x00007FF9974E38C7 (XAudio2_9.dll) in Game.exe: 0xC0000005: Access violation reading location 0x0000025274A680C4.". I am assuming that the xaudio2 thread is still trying to read the buffer even though I have disposed of it. I have set it up in a way so that there is a central SoundSystem class which has 2 vectors of Voices(another class), idleVoices and activeVoices. when I play a sound I grab a voice from the idle channels and play a sound, then when it is done I put it back in the idle channels and repeat.

            You should add a call to StopEngine in the WM_CLOSE. This will stop all processing of the worker thread and likely resolve your crash.

            Why is QueryInterface() returning E_INVALIDARG?
            Asked 2020-Dec-03 at 08:37

            I was coding a project and I came across a bug where QueryInterface() was returning E_INVALIDARG, I don't know which argument is invalid because both arguments are simple enough, am I overlooking something simple or what?

            The bit that that is failing comes from Microsoft themselves specifically documentation, if I'm doing something totally wrong tell me

            ...

            ANSWER

            Answered 2020-Dec-03 at 02:02

            There are only 2 parameters to QueryInterface() for E_INVALIDARG to complain about, and offhand they look fine to me inside of your CreateSecondaryBuffer() function. The 1st parameter is being passed a hard-coded IID, so the problem has to be with the 2nd parameter, which expects to be passed a pointer to (in this case) an IDirectSoundBuffer8* variable that QueryInterface() can write the memory address of a DirectSoundBuffer8 object into. So most likely, the ppDsb8 parameter of your CreateSecondaryBuffer() function is not being passed a valid pointer to a IDirectSoundBuffer8* variable, like you are expecting.

            UPDATE: After seeing your added comment, you are indeed passing an invalid pointer to the ppDsb8 parameter of CreateSecondaryBuffer(). The caller's pMainSecondaryBuffer pointer is being declared incorrectly, and is uninitialized when passed to CreateSecondaryBuffer(), so you are passing a bad pointer to QueryInterface(), hence the E_INVALIDARG error.
