flashjazzcat Posted June 8, 2018 Share Posted June 8, 2018 AVG should also handle the PDM player perfectly well, given the positive direction taken with firmware development there. 2 Quote Link to comment https://forums.atariage.com/topic/279232-fujiconvert-01/page/6/#findComment-4044106 Share on other sites More sharing options...
Mathy Posted June 8, 2018 Share Posted June 8, 2018 (edited) Hello guys Just tried to FujiConvert the theme from James Bond. Don't know what happened, but the resulting sample sounds way different from the original. I've just now FujiConverted eight songs. Seven of them sound just like the original, "James Bond" sounds different. If anybody is interested to check out what went wrong during FujiConversion, I can send you the original and the sample file.

Xuel Posted June 8, 2018 Author Share Posted June 8, 2018 Hello Xuel Just tried FujiConvert 0.2.1. At first I thought I had done something wrong. But if you press the space bar when asked to press any key, the sample won't play until you hit the space bar again. Oops. And could you please add the option to choose between "start over" and "stop" when the end of the sample is reached? Sincerely Mathy Good point. This happened because I added space as a play/pause toggle. I'll fix the keyboard routine so it doesn't think the "any key" keypress is a keydown event for the play routine. I'll also put a loop/stop toggle on the todo list. And Escape to return to the splash screen. 4 Quote Link to comment https://forums.atariage.com/topic/279232-fujiconvert-01/page/6/#findComment-4044180 Share on other sites More sharing options...

Xuel Posted June 8, 2018 Author Share Posted June 8, 2018 Hello Xuel The James Bond Theme.zip Sincerely Mathy The only thing I would suggest is reducing the Gain parameter to 1 for this song. This song spends most of the time using the full dynamic range, so by using FujiConvert's default gain of 1.5, you get a lot of clipping. Here it is with Gain set to 1: The James Bond Theme pcm4+4 stereo 32760Hz atarimax pal.zip 1 Quote Link to comment https://forums.atariage.com/topic/279232-fujiconvert-01/page/6/#findComment-4044712 Share on other sites More sharing options...
Mathy Posted June 8, 2018 Share Posted June 8, 2018 Hello Xuel Thanks. It sounds better, but still isn't anything near "perfect". Would values like 0.9 or 0.8 work?

Xuel Posted June 8, 2018 Author Share Posted June 8, 2018 Hello Xuel Thanks. It sounds better, but still isn't anything near "perfect". Would values like 0.9 or 0.8 work? Sincerely Mathy Perhaps. Are you listening on real hardware? It could be that you're hitting the saturation that phaeron described here. Going below unity gain could help in that case. This song also has a lot of low bass. So perhaps that is interacting badly somehow. The Atari's audio circuit has a high-pass filter to get rid of any DC offset. Maybe it's attenuating the bass.

phaeron Posted June 9, 2018 Share Posted June 9, 2018 Source wave vs. recorded wave from 130XE. Looks like a combination of noise from hi/lo channels not quite matching up either in time/amplitude and distortion from the output circuitry. 3 Quote Link to comment https://forums.atariage.com/topic/279232-fujiconvert-01/page/6/#findComment-4044971 Share on other sites More sharing options...

The waveform is just a single PM register, using FF for data (with all DMA turned off). So I believe by setting the colour register for that player, you can get any single colour you like.

+Stephen Posted June 12, 2018 Share Posted June 12, 2018 (edited) Tried another conversion today (been listening to a ton of Jonathan Moffet via youtube). I'm not pleased with the results. I tried various gain settings from 0.75 up to 2.0 and there is always a "fuzziness" through the entire song, not just the quiet parts. It's not clipping. I am thinking it's a distortion related to the high dynamic range, and the quiet parts will always have this noise. 06 - Billie Jean pcm4+4 mono 44270Hz ide pal gain 2.0.zip Edited June 12, 2018 by Stephen Quote Link to comment https://forums.atariage.com/topic/279232-fujiconvert-01/page/6/#findComment-4047318 Share on other sites More sharing options...

tmp Posted June 23, 2018 Share Posted June 23, 2018 not sure if that's related but fjc's IDE PDM player has currently file size limitation (due to sector table it builds) so be sure to experiment with shorter tracks first 2 Quote Link to comment https://forums.atariage.com/topic/279232-fujiconvert-01/page/6/#findComment-4055095 Share on other sites More sharing options...

Mclaneinc Posted June 24, 2018 Share Posted June 24, 2018 Gents and ladies. lets not get too carried away after perfection, remember these old machines use hardware not really looking to produce CD quality sound I am awestruck at the quality of the noise coming out of my 130XE and Altirra, its so much better than the stuff from back in the day but its also using resources that we didn't have then or it was in its very infancy (ram upgrades). Tune away but I saw the words "its not perfect" and I just wanted to remind folk that there's 40yr old design factors in the way It sounds amazing though and I love the vigour from all the folks putting time in to this and I'm proud that its the Atari doing the work, it would be so easy to add a sound producing board but then its not the Atari itself.. 2 Quote Link to comment https://forums.atariage.com/topic/279232-fujiconvert-01/page/6/#findComment-4055799 Share on other sites More sharing options...
