[mad-user] Using MAD with a 24-bit sound card
Wed, 29 Nov 2000 06:46:16 -0600
I've been using MAD with an M Audio Audiophile 2496 card for a week
now. Here's what I've found.
The oscilliscope and VU meter is useless in 24 or 32 bit resolution
mode; it just constantly squiggles, even during silent passages. With
my particular card, 24 bit resolution only works with a waveOut buffer
of 9000 ms or more. If I use a lower buffer, the MP3 files will start
"screeching", making nothing but a loud static noise if I scan through
the song. However, 32 bit resolution works fine. MAD's 32-bit output
is padded 24-bit, correct Rob? Well, I'm using it with my 24-bit sound
card, and it works perfectly with the default waveOut settings.
And like I even need to say this, MAD at 24-bit resolution blows
Fraunhofer or audioEnlightenment out of the water. I'm using a Creek
OBH-11 headphone amplifier mated to Sony MDR-V6 Studio Monitor
headphones, and the difference is pretty stark and obvious. The MAD
output sounds more natural, has better instrument decay, has more bass
power, and the bass is smoother and the treble clearer. Fraunhofer
sounds positively fake in comparison.
Regards to you all,
