Audiovation and CoolEdit v1.53

The purpose of this page, is to show how you can use your Audiovation soundcard for MCA to do som actual work.
In order to manipulate soundfiles, you will need a soundeditor, just like you would need a wordprocessor to manipulate text. My choice for doing soundediting is Cool Edit version 1.53 from Syntrillium. I tried a newer 32 bit version some time ago, but it was mute. Before I go into further depts with this, a bit about my hardware set up, so you can compare, if you get funny performance:

IBM9577i *Lacuna* with IBM 9525 monitor doing 800x600x65K
The latest BIOS upgrade installed
CPU AMD 5x86 aka Kingston Turbochip 133
L2 Cache 256KB
SCSI-2 FW aka Corvette
SCSI harddrive Viking II 4G7
SCSI CD-RW Philips CDD3600 with 1MB cache off a FD-600
Audiovation Soundcard
Multimedia panel 41G3929 (Amplifier, speaker, volumecontrol, 6.3mm phone and micjacks)

Since sound files in the *.WAV format, 44KHz sampling frequency, 16 bit stereo (CD quality) consumes approximately 173KB/second, 2GB drivespace is a minimum, if you want to hold the equivalent of 74 minutes of CD music on top of everything else. The Philips CDD3600 writes at x2 quite reliably, courtesy to the large cache, minimizing risk of buffer underrun. It reads at x6, but the reading is rather sluggish, compared to any off the shelf CD-ROM. And it reads really bad when the system has been running for an hour, and things get hot.

Now we have been through the hardware motions, a bit about the operating system:
Windows 95B OSR2 (Danish). The sluggish reading by the Philips CDD3600 is somewhat improved, by editing c:\windows\system.ini so it has the lines:


The numbers prevents win95 from eating all of your RAM, and should not exceed 25 percent of your ditto.
If you intend to do editing of soundfiles extracted from CD-Audio, which is common CD music converted to a format a computer can handle, without any analog intermediate, you can technically use CoolEdit for the extraction proces. I will recommend you use some other software for the extraction proces. CoolEdit is limited to SCSI, and is very inflexible when it comes to finetunings, getting stable strippings.

CoolEdit can handle mp3 music, but again, rather poorly. More below.

Now let's take a look at the CoolEdit stuff. CoolEdit v1.53 was designed for Windows 3.x, but works nicely under Windows 95. I don't know whether Syntrillium still market this product, but as of 25th aug 2000 there was nothing om their Internet site, except for the patch. (Yes - they goofed first time around too). They do however explain the difference between v1.53 and newer pure 32bit versions. A download can be made from:

If the above link lames, mail me.

Don't forget to get the patch from: (Patch repairs something that went wrong in the first try) 248KB

It is shareware, and you are supposed to pay a fee (US$50 as of march 1999) to Syntrillium and register. If you don't, you can use it anyway. If you have not registered, you have to choose between features every time you launch the program:

When you launch a registered version, the above is skipped, and you go straight into something like:

The above image tells several things. All the greenish stuff reveals the waveform of a song popular with the president of a certain union. (Not the one I live in, it has no president - only commissars). Lets say, your aim is to take a soundbite out of the chorus where they go *don't stop thinking about tomorrow* You simply leftclick on the *Play* button and watch the vertical ruler follow the music flowing through your Audiovation into your hifi:

When you visually have a feeling of where the bite part begins and ends, stop the playing, and mark the section as you would mark parts of text with a wordprocessor.

Hit the *Zoom In* button, to make the selected part fill out the screen

Do further refinements, and save your work. There is a lot of refinements you can do, fade in, fade out, raise the overall level and who knows what. If you want to make a nonstop party CD, you can use CoolEdit to cut all the leading and traling silence of each track. In basic it works like any other cut and paste job, and only imagination -etc. Click on the image above and listen. The eight seconds are converted from CD quality WAV to RealAudio, since I am a nice person, who would rather load you with 21KB than 1.4MB. Talking about RealAudio: I think I once lied to Louis Ohland, by telling him that 32bit players will not work with Audiovation. This was not true. The 32 bit Real Player version 5.0 from 1997, and the later G2, works ok with Exploder 5.01DK. Haven't tried the latest version 8.

One thing though. In the *Options* -> *Settings* you should reduce the default number of *Undo* from 5 to 1, or even zero. The undo facility eats resources, and if you don't have them, CoolEdit might get stuck, and you have to do a ctrl-alt-delete. Same place you might change the default workplace to suit your particular configuration. (Place *Temp* and *Undo* at disk with largest empty space).

Thats allmost all about it. I mentioned mp3 earlier. This is an area I haven't worked too much, since my PS/2 don't have the muscle to play mp3 in stereo. Mono ok, but not stereo. CoolEdit v1.53 can handle MP1-3 with the addition of some patches. It do spent some time converting between mp3 and wav, and I'm not shure whether the *.mp3 file extension works. You are on your own, after you have downloaded the additional patches here

mp3 135KB
