I am running into some problems finding a solution when it comes to performing some form of Bluetooth connection check for my project that will allow me to have a connection status light.

I am planning an app that would take music playing on the system, find the key and bpm of the song, and then visualize the music based on that information. It is crucial that the visualization is synced exactly with the music, but as finding key and bpm almost certainly requires sampling ahead, the visualization ..

I do know how audio works and how to generate sample arrays to represent the audio. What I want to know is how to interface my program with my computer’s speakers I’m on Windows ..
To begin, I run this command to set all of my pipeline elements to paused: int ret = gst_element_set_state (pipeline, GST_STATE_PAUSED); Next, I check all of my pipeline components to ensure that they are in the paused state (which they are): GstElement(imagesaver), status = PAUSED, pending = VOID_PENDING GstElement(saveImageTee), status = PAUSED, pending = VOID_PENDING ..
I am working on a synthesizer/live-coding application where I want to have multiple instances of the engine generate different sounds with different sequences. (aside: I have the synth engine working with MIDI input). Let’s say the user input to the console may look something like this: track:1,sound:pad,seq:[70, sleep 0.25, 77, sleep 0.5] track:2,sound:bass,seq:[30, sleep 0.125, ..
I am developing an application that record the screen and the audio from microphone. I implemented the pause function stopping video and audio thread on a condition variable, resuming them with a notify on the same condition variable. This is done in captureAudio(), in the main while. In this way works on macOS and linux, ..

Everything was good with Windows 10, however audio quality is so bad now. Is there a way to install B&O drivers in my new operating system ..
