Rockbox mail archiveSubject: MP3Buffer?MP3Buffer?
From: George Styles <george_at_ripnet.co.uk>
Date: Fri, 9 Aug 2002 11:25:12 +0100 how big is the internal MP3 buffer in the MAS chip? i assume that it uses DMA to load in a new buffer from 'main' ram every time it runs out, but how often does it do this? the reason I ask is that I want to try and implement a 'beep' when a remote control button is pressed. My idea is to overwrite the buffer in main ram with a 'beep' mp3 frame, and wait for it to be DMA'ed to the MAS chip. Obviously this is not gonna be good if there is a 1s or more delay before it is loaded in. Could we do something else to the MAS chip to feedback? like maybe set all bass/treble/loudness DSP settings to max for 1/10s to make it sound different for a bit? cheers g Received on 2002-08-09 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
