Final answer:
In Ableton,Option c) Buffer Size affects recording latency by determining the number of audio samples processed at once.
Step-by-step explanation:
The function in Ableton that affects recording latency is C) Buffer Size.
Latency is the delay between an input being processed and the corresponding output. This is particularly important in audio recording and production, where latency can cause issues such as noticeable delay between playing an instrument or singing and hearing the playback. The buffer size determines how many audio samples are processed at one time. A smaller buffer size results in lower latency but can put more strain on your computer's CPU, potentially leading to audio dropouts or glitches if the CPU can't process the audio fast enough. Conversely, a larger buffer size increases latency but provides a more stable performance, especially with complex projects or when using a lot of plugins.
