The Ogg Vorbis (CLI codec for Pentium 4 only)

[neilthecellist]

Is it possible to use the Ogg Vorbis CLI codec on a non-Pentium system?

I'm using the latest dMC (unregistered [I'm gonna buy it soon] ) on a Celeron 733 mhz Celeron.

Also, is there a way of speeding up audio conversions? When I convert, say, a .wav file to .mp3, it's at 4x a second, whereas on my brother's computer it's usually around 8x....It seems to me that dMC is CPU-dependent; my CPU is always at 100% when I convert something....

The Ogg Vorbis P4-only CLI Codec will fail on any non-Pentium 4 System. You can still use the normal Ogg Vorbis codec, though.

And yes, converting files to compressed formats are CPU-dependent mostly, but also depend on other factors.

could i speed it up by setting the CPU priority to Realtime under Task Manager (or on the latest dMC release itself)? Would I lose audio quality by driving my CPU to its max?

Re: The Ogg Vorbis (CLI codec for Pentium 4 only)

No, raising the priority would not reduce the audio quality, but will result it you not being able to use your computer while it's converting.
Also, if your ripping a CD, this is a bad idea, as there are two threads running when you rip a CD: CDGrab.exe ripping the CD and MusicConverter.exe converting the ripped song.

Edit: Also, what is the clockspeed of your brother's computer? How much RAM does your computer have? Is the conversion speed you stated for converting one file to another or for ripping a CD?

What if I used Alcohol 120% to take the CD image and mounted it to a virtual drive? Would it still be a bad idea to raise the CPU priority?

What do you mean by my brother's clockspeed? You mean his CPU? It's a Pentium 4 1.8 Ghz Processor. My computer has 128 mb of RAM clocked at 133mhz, one stick. My brother's memory is 768 mb, one stick 512 at 266 mhz and another stick of 256 mb at 266 mhz as well....


I'm doing both. Ripping and converting audio files...

Re: The Ogg Vorbis (CLI codec for Pentium 4 only)

If you have not already made a CD image, it would end up being about as fast to go ahead and just rip the audio from the CD and not make an image. Either way, the conversion to mp3 will still take a good while to complete, due to your slow CPU and low amount of RAM.

Also, whenever you rip a CD, if you set the dMC priority to Below Normal, it rips faster. This is because the conversion then gets a lower priority than the CD ripping. You can always set it to normal, of course, but setting the priority any higher will result in a longer time to rip the CD, due to the CD ripping thread having to fight the conversion thread for CPU access.

Priority is just how much time windows gives to dMC in relation to other programs, if there are no other programs running there is nothing to be gained.

What about my harddrive speed? Does that significantly affect conversion speed in dBpowerAMP Music Converter? My harddrive speed is ATA 100.

No, encoding Ogg is 1000x slower than Hard disk writing.

A THOUSAND TIMES SLOWER? Are you serious?!!

Same question from me. I encode to OGG all the time using DMC to send music files to friends and the encoding process takes seconds.

Re: The Ogg Vorbis (CLI codec for Pentium 4 only)

Yeah, i know, adaywayne, how can it be 1000x slower?

Re: The Ogg Vorbis (CLI codec for Pentium 4 only)

Spoon has said before that Ogg encoding is the slowest compression. I've notice this also, in that I can rip a CD to Monkey's Audio in the same time it takes for me to convert that CD from Monkey's to Ogg.

And neil, the ATA100 speed is good. However, the rotation speed of your HDD is even more important. Do you know if the drive is a 7200RPM or 5400RPM drive? Or even 4200RPM?

I still think the limiting factor, neil, in your performance is your low CPU speed. How long does it take for you to rip a CD to a lossless format, like WAV?

[COLOR=Navy]This is a question, not an assertion, but in converting from Monkey's to OGG, is the process not going in two stages.....Monkey's decompression standard wave and then wave to OGG?

It depends. Do you mean like a FULL 80 minute CD?
