audio-recording

I am taking my first dives in to the WASAPI system of windows and I do not know if what I want is even possible with the windows API. I am attempting to write program that will record the sound from various programs and break each in to a separate recorded track/audio file. From the reseacrch I have done I know the unit I need to record is the various audio sessions being rendered to a endpoint, and the normal way of recording is by taking the render endpoint and performing a loopback. However from what I have read so far in the MSDN the only interaction with sessions I can do is through

I'm trying to get the sound input and send output directly with less latency possible with C#. I'm using the library NAudio that supports ASIO for better latency. In particular, I use the AsioOut object for recording and another for playback initialized with a BufferedWaveProvider , which is filled in a Callback function: OnAudioAvailable , which allows me to use the ASIO buffers. The problem is that I hear the sound with various glitches and with a bit of delay . I think the problem is in the function OnAudioAvailable where the buffer is filled with data taken as input from the sound card.

How can I do audio recordings using android.media.AudioRecord without any smartphone-manufacturer-dependent fancy signal processing like automatic gain control (AGC) and/or equalization, noise suppression, echo cancellation, ... just the pure microphone signal? Background MediaRecorder.AudioSource provides nine constants, DEFAULT and MIC initially being there, VOICE_UPLINK , VOICE_DOWNLINK , and VOICE_CALL added in API level 4, CAMCORDER and VOICE_RECOGNITION added in API 7, VOICE_COMMUNICATION added in API 11, REMOTE_SUBMIX added in API 19 but not available to third-party applications. But
