H/w buffer tracking vs mix

hey guys, i looked around a few threads and couldnt get a straight answer. It seems like when tracking the buffer size should be set lower. and when mixing the buffer should be set higher. Im running PT m powered on a macbook. just trying to get a general idea of what other people track and mix at.

That's pretty much how it works. You want the lowest you are comfortable with when tracking. The lower the buffer, the more computer processing it uses. Depending on your interface, you may be fine with even 128, without even having to go down to 64 or 32 (some newer interfaces are faster than some older ones, even at the same buffer).

The higher your buffer, the less processing it uses. So for mixing, you can set it high. The slight bit of delay doesn't matter in that case because you're just listening back.

However, in Protools, sometimes the timing of midi sequencing can be a little off when using higher buffers. As you go along, you may want to record your virtual instruments to audio tracks, and do so at lower buffers (you can deactivate other tracks to help with processing). After you've recorded them to audio tracks, you can deactivate the midi/instrument tracks.

wicked. lol thanks man. its kinda hard to get a solid explanation like that from people in person. theres alot of uuuh and likes. in there. so thanks haha.

It's all about latency. Use the smallest buffer you can get away with.

yeah experimentation is the key i guess. i was just trying to get a general yay or nay to avoid a bunch of DAE errors during tracking.

You only need a small buffer size if you want to monitor the incoming signal in real time INCLUDING some plugin fx (e.g. some reverb on the headphones while singing or playing a virtual instrument). The small buffer size prevents the monitor signal to be delayed (by the amount of buffer size), which is kind of annoying for the performing artist. If you're using a mixing console for monitoring or if you're using a direct monitoring feature on your audio interface, you don't even need a small buffer size during recording.
Typical buffer sizes for recording are 32-128.

A small buffer size puts more strain on your DAW's performance, because each time the buffer "runs out", the CPU gets interrupted and the sample data within the buffer needs to be transferred to the audio interface and back. If running at 44.1KHz sample rate, we talk about 44.100 samples per second. A buffer size of 32 samples causes 44.100 / 32 = 1.378 interrupts per second.

That said, the buffer size should be as high possible and as low as needed.

For mixing, a small buffer size does not have any benefit. Thus typical buffer sizes for mixing are 512-1024.
