Total recorded sample length

[D S Sreedev]

Hi, I have a basic doubt. The Audio Hacker has 256 K serial SRAM to store audio samples. It is equal to 262144 Bytes. But as per the memory capacity table given in the project page, if we use say, 22 kHz sampling rate with 8 bit resolution, the total sample length could be stored is 12.9 sec. Actually for this settings, there will be 22000 x 12.9 = 283800 Bytes data. Is n’t it? But the SRAM has only 262144 Bytes storage space. So how this will be stored in SRAM? Please help me to understand this..

You’re right, 262144/22000 = 11.9s.
I’m not sure how I came up with 12.9 in the documentation. It was many years ago.

Thank you very much for the clarification..
