Clarification of Epoch interval parameter

[yannickadam]

Hi, and thanks for this library!

Looking at the doc for Epoch, it is mentioned:
* @param {number} [options.interval=100] Time (ms) between emitted Epochs

However, a bufferCount(interval) is used to accumulate the samples. To really emit every 100ms, in the case of a sampling rate of 256Hz, an interval of ~26 would be needed.

Could you confirm?

Hey @yannickadam,

Thank you so much for all of your contributions!

As per your question, yes, that's exactly correct.

We actually use an interval of 25 in Neurosity OS (which uses eeg-pipes on embedded hardware) for our Notion EEG device.
