Date: Fri, 15 Feb 2002 14:23:45 +0100 (CET) I recently got myself a second Archos, a Recorder 20. I figured I should have both a player and a recorder if we're going to write code for both. The Recorder is really nice, with much more powerful audio. Unfortunately, it also has a very faint, but noticeable, noise in the audio output. At first I didn't think it would bother me, since it isn't noticable while the music is "normally loud". But I listen movie scores a lot and they often have long sections of very still and quiet music, in which the noise is very annoying. I figured with all the electronics wizards in here, we could perhaps try and analyze what the noise comes from and if there's something that can be done about it. The noise is most apparent during playback (including in paused mode), possibly due to the VU bars that are updated on the screen. It then has a oscillating sound at a frequency of maybe 10-15 Hz. If I bring up the menu or another screen without the VU bars (during playback), the oscillating stops and there is a instead a steady white noise. Stopping playback stops the noise. Also, the noise goes away during disk access. Ideas, anyone? -- BjörnReceived on 2002-02-15 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
