Noise on AIFF files when burning Audio CD

[emonod]

Hi everyone,

 

We've got a weird problem.

 

When reading AIFF files that were added to Toast 7.1.2 to burn an audio CD, there is a weird noise, like an interference (sputtering? in french, "gresillement"). The same noise can then be heard when reading the burnt CD on any other audio device. The files are 48 KHZ, that were exported from Final Cut Pro via QuickTime version 7.0.4. We encounter this problem on a PowerBook G4 10.4.11.

 

The problem disappears if we export the aiff file to 44.1 KHZ with quicktime before drag-and-dropping it into toast. It seems that toast is not converting the file anymore from 48 to 44.1 KHZ?!?

 

Now where the problem become mind bugging, is that 48 KHZ AIFF files do not have the noise problem at all when the CD burning is done on another computer (Powerbook G4 10.3.9). The toast version installed on that computer is the same (7.1.2) but the quicktime version is 7.3.1.

 

Any clue anyone?

Hi Imor,

 

You've almost located the problem!: what we found out, is an incompatibility between Tiger 10.4.11 (which is very close to the new OS Leopard) and Roxio 7.x I've read on other forums that Toast 7 is incompatile with Leopard - so that's the reason of the bug.

 

So how to solve it?

 

1. Go back to Tiger 10.4 using your installation CD (use the option install and archive)

2. Go to http://www.apple.com/support/downloads/mac...oupdateppc.html and dowload the 10.4.9 combo update (10.4.9 is the last "safe" update of Tiger as far as I know. Not so sure about 10.4.10, so in doubt, stick to 10.4.9).

 

You'll see the noise disappears. Yeeehaaa!!!

The quicktime version has no effect on Toast, but in case you also work with Final Cut, be aware that Quicktime 7.3.x is incompatible with Final Cut Pro HD 4.5... The last "safe" version of Quicktime to my opinion is 7.2 and it works just as fine.

 

All this makes me think that one should NEVER update automatically softwares - if your systems works fine, stick with the original versions as long as possible!!!

 

 

emonod,

 

Good show. Now, if I just hadn't bought Leopard. Thankfully I installed it on an external drive. The darn thing broke just about any application I have plus the link to my remote printer.

 

I don't remember such a piece of crappy operating system since 10.0 6 years ago.

 

I guess everybody forgot how to test SW, it is obviious they don't know how to write it....

 

And this goes for both Apple and the developers.

Hi,

 

I have the same problem. The symptoms are identical.

 

Powerbook G4 (Aluminum)

Tiger 10.4.11

Toast 7.1.3

QuickTime 7.3.1 (I wonder if this is relevant)

 

The original MP3 Audio file, when burnt, had all the symptoms emonod described. I thought that maybe the conversion to AIFF by Toast was at fault.

So I converted the file to AIFF with Amadeus II and burned it: no change, same noise. So I converted using Switch and burned it: no difference.

 

On the same machine I have a separate partition running Panther 10.3.9 and the same versions of QuickTime and Toast as the Tiger partition: the file burns fine with no noise (either converted file or the original MP3 file).

 

In addition, I tried the burn with Toast installed in the Tiger partition and with Toast called from the Panther partition into the Tiger partition after completely removing Toast from the Tiger partition (including the .plist file) : no difference, same noise.

 

Audio file(s) info:

 

MP3 - Sampling rate :22050 kHz, 16bits

AIFF - Sampling rate : 22050 kHz, 16 bits

Burnt file : 44100 kHz, 16 bits

 

That's a lot of burns of a 631MB file! The bug has to be in Tiger.

 

Any ideas ?

 

Thanks
