VQF FAQ
What is VQF?
VQF is a new recording
format, like MP3, but better in a couple of ways. All of
the things about it will be explained below, and if you
still have any questions, please feel free to e-mail
me.
1. File size:
VQF files are
approximately 30-35% smaller than MP3 files, when
comparing a 128kbps MP3 to a 96kbps VQF. For example,
take a 5 minute song. The WAV file you would rip off
the CD would be about 50MB, depending on the quality.
If you were going to encode that as a MP3, @ 44khz
and 128kbps, it would end up being about 4.5MB, and
some sound quality loss. If you were going to take
the same file and encode it as a 96kbps, 44khz VQF,
it would only be about 3.5MB, and have better
quality. Too good to be true? listen to each type of
file for yourself and find out! An 80kbps VQF file is
the same quality as a 128kbps MP3.
2. Sound
quality:
As already said above,
the sound quality is much, much better. Another
example is take a WAV file and encode it as a 256kbps
MP3 file, it would be about 9MB, but close to CD
quality. But why would you do that when you could
encode the same song as a 96kbps VQF and have the
same quality and in a file 1/4 the size?
3. CPU usage:
Okay all you MP3 fans,
this is the only bad part about VQF's, they use more
of your processor power. Hey, it's not all bad, you
have to sacrifice something for better quality. Why
is this? Well, when the VQF format was introduced,
Pentiums were everywhere, and they could handle it,
unlike my 486/66. Now, Pentium II's are getting much
cheaper, and are more popular, so they can use more
of your processor, with plenty speed left for
everything else. For example, a 128kbps MP3 on a
Pentium 233MMX uses about 15-20% of your processor's
power, while a VQF uses about 30%, it's not that bad.
If you have a slow computer, use the files in my
archives, they play fine on a 486/50 with 20MB RAM,
just don't do anything else :)
Drawbacks:
1. Few Files
VQF's are new, very
new, so there aren't as many files out there, as
there are MP3's, only about 1500 VQF's total,
compared to tens of thousands of MP3's, but if you
want to help the VQF community grow, encode your CD's
and upload them, or decode MP3's (can you???) and
encode them into VQF's.
2. Slowwwwwww
Encoding
This is probably
because of two things, one, being the most likely, is
it takes more time to put more stuff in less space.
The other one ties in with VQF being new. Since it is
brand new, there hasn't been much time to refine the
encoding engines and speed up the process. Other than
that, there is nothing slowing it down.
Want to know how fast
it will be on your system? A Pentium 233MMX will
encode a 50MB WAV file in 10-15 minutes, if the
priority is set to high. With the newest encoder by Yamaha, you can encode many
files at once, or encode your files in batches, or
many files, one right after another. Great for over
night.
System
Requirements
- Windows 95, 98 or NT 40.
- For encoding:
- 486 66 minimum, 200MMX
recommended (don't use a 486 for
encoding, it's not fun)
- 16MB RAM minimum, 32
or more recommended
- For quality playback:
- Pentium 90 minimum (75
will run, however), 200MMX recommended
(50MHz for my files)
- 16MB RAM.
Just a hint, if your computer can
play MP3's fine, you will probably play VQF's without any
problems, but if it struggles with MP3's, don't even
waste your time downloading the songs, unless they are
from my archive ; )
