As I think Neil pointed out in a post coming up, old 486 systems with 8MB used to be able to record audio pretty darned well. So there may just be some tweaks I need to discover to get this WavJammer going. I remember using my old 486sx33 with 4 meg of RAM and a SB Pro to do audio work ... but remember, back then the quality wasn't anywhere near as good and the hardware wasn't as bloated (remember, shoving audio through a USB cable is a lot of work for a slow processor). The OS (MS-DOS at the time) wasn't as bloated either! More to the point, most of the software didn't go anywhere near the OS - in the days of W3, you could ignore any other processes on the system, and for audio, you did. It was reasonably easy, even on things as slow as 486sx33 or even 25, to do useful things if your program was the sole user: I had a 25 running a display for the World Service, with sychronised cross-fading graphics displays, real time control of external hardware and pushbuttons, and able to play a cue track, record to the disk, and replay to an external tape machine simultaneously... it's not hard when MS doesn't get it's fingers in the pie. _ Chat with friends online, try MSN Messenger: http://messenger.msn.com ** http://libretto.basiclink.com - Libretto mailing list http://libretto.basiclink.com/archive - Archives http://www.picante.com/~gtaylor/portable/faq.html - FAQ ---TO UNSUBSCRIBE--- Reply to any of the list messages.

Re: AW: [LIB] recording audio? (danger technical)
Date: Thu, 28 Mar 2002 09:20:37 From: neil barnes [EMAIL PROTECTED] Subject: Re: AW: [LIB] recording audio? (danger technical) This guy Karsten Krause posted to the list back in 1998 about his Roland SCP-55 sound card for his Lib that he seemed quite pleased with. I may just keep an eye out for one of those on EBay if I can't sort out these quiet little clicks in the recorded signal from the WavJammer. Matt - are these clicks very regular? Have you looked at them with CoolEditPro or similar? Are they recorded artifacs or replay artifacts? A major problem with sound and windows is that the hardware to record/replay sound relies on DMA transfers to get the data into/out of ram. There are restrictions on the hardware (it has to be in the first 16M of memory, it can't cross a 0x000 boundary etc) which don't tie in well with windows - windows wants to decouple physical memory from logical memory. There are libraries which do varying degrees of damage to utilisation rates as they try to present a decoupled view (the X-audio libraries) You may find it necessary to drop into dos mode and do your recording there, if only to avoid the overhead and context switching. In a worst case, it's possible that the OS is reading bits one at a time :) If you want to write code, I have the reference manuals for the soundblaster chipsets - though that may not be effective for your system.

All you need to do is turn one of the Libs up-side-down :-) Sometimes I prefer to have the keyboards side-by-side, or, for games, it is OK with 2 Lib50 back to back (direct beam), but with Lib50 and Lib100,and direct beam, the Lib50 owner can see the Lib100 screen.
