Audacity is a free and open-source digital audio editor and recording application software, available for Windows, macOS, Linux, and other Unix-like operating systems. [4] [5] As of December 6, 2022, Audacity is the most popular download at FossHub, [8] with over 114.2 million downloads since March 2015.
ASIO 2.3 introduced monitoring for dropouts in the audio stream. [4] ASIO bypasses the normal audio path from a user application through layers of intermediary operating system software so that an application connects directly to the sound card hardware. Each layer that is bypassed means a reduction in latency (the delay between an application ...

A sound card (also known as an audio card) is an internal expansion card that provides input and output of audio signals to and from a computer under the control of computer programs. The term sound card is also applied to external audio interfaces used for professional audio applications.
Control channels Controlled source Wave / PCM stereo: Audio signal generated by the CPU via the sound card's digital-to-analog converter. (This includes audio produced by games, MP3 or WAV players, but also some software playing a CD-DA through the CPU, such as, Windows Media Player or Media Player Classic, as well as TV tuner cards that use the CPU for decoding audio.)
Spill occurs when sound is detected by a microphone not intended to pick it up (for example, the vocals being detected by the microphone for the guitar). [3] Spill is often undesirable in popular music recording, [4] as the combined signals during the mix process can cause phase cancellation and may cause difficulty in processing individual tracks.

However, in the process I stumbled a bit into the question of which features of Audacity are important, which aren't and what's run-of-the-mill. In particular, I'm unsure about: Individual effects (change tempo, noise reduction, vocal reduction are directly mentioned, but a lot more could be mentioned)
When resampling audio to a notably lower pitch, it may be preferred that the source audio is of a higher sample rate, as slowing down the playback rate will reproduce an audio signal of a lower resolution, and therefore reduce the perceived clarity of the sound. On the contrary, when resampling audio to a notably higher pitch, it may be ...
