Subject:audio degradation Posted by: daize Date:6/16/2006 1:35:07 PM I have taken a song in stereo .WAV form, beatmapped it, loaded it into Acid 6, and re-rendered it with the beat map info. No other processing, level changes etc were carried out. Doing an A/B comparison with the original .WAV, the sound of the new .WAV is markedly degraded (bass light, middle feels like sounds are dropping in and out). It is not my system because I tried this on my lap top also with the same results. Can anyone shed any light on this before I go back to Acid 4. Thanks
Subject:RE: audio degradation Reply by: jbolley Date:6/19/2006 10:29:51 AM It sounds like you've used beatmap to 'quantize' the original wav. Can you play them togeather at the same time? Do they shift in time?

Subject:RE: audio degradation Reply by: vespesian Date:6/19/2006 10:58:43 AM What WAV template did you use? (there are at least 12 custom 'pre-sets', half of which are mono, with varying sample rates); and several different formats, as well....when you render click the templates button - but also the 'custom' and 'about' button - I bet you accidently recorded in mono, or different bit-rate, or something like that...

Subject:RE: audio degradation Reply by: daize Date:6/19/2006 5:15:24 PM Thanks guys for replying. I have been an Acid software user since Acid 3.0 and really know my way around the programme. When I have to edit a mastered track quickly (remove sections or restructure etc) I beatmap to find the tempo, then put the .WAV into Acid to do my stuff. I do not alter the tempo, key shift or do anything that might change the quality of the audio - it's simply chop, chop, then render back to stereo 16 bit 44.1. I have used this technique successfully with Acid 3, 4 and 5. But for reasons as yet not clear, Acid 6 seems to suck the life out of the audio during the process. Maybe a Sony techie can shine some light on this? Cheers Daize
