50 Korg 1212 I/O
English
Audio
Audio has pops and clicks
OR
The same audio sounds different between ADAT, S/PDIF, and Analog
inputs or outputs
OR
ADAT or S/PDIF inputs or outputs sound distorted
Make sure that the word clock settings are correct for all hardware and
software, including ADAT-compatible multitracks, digital mixers, S/PDIF
devices, and digital audio software.
Audio playback is very slow and low-pitched
If the digital audio program’s word clock source is set to S/PDIF•Word
Clock (in Deck, this is called “Digital”), is there a device connected to the
1212 I/O’s S/PDIF or Word Clock input?
If the digital audio program’s word clock source is set to ADAT, is there a
device connected to the 1212 I/O’s ADAT optical input?
If the connections are correct, is the S/PDIF, Word Clock, or ADAT device
turned on? Note: Some early DAT players may not output S/PDIF word
clock when stopped.
If Deck is running at the same time as another 1212 I/O-compatible
application, Deck does not automatically reset the 1212 I/O’s sample rate,
clock source, or analog input level when switched to foreground. To reset
the card to match Deck’s settings, go to the Hardware Configuration dialog
box, and press OK.
Audio playback is slightly slow, or slightly fast
When you record or play back audio data using external clock sources
(such as the S/PDIF, ADAT, or Word Clock inputs), the sample rate is
controlled entirely by the external source, and not by the digital audio
program’s sample rate parameter. Because of this, you must make sure that
the external clock source is actually set to the same sample rate as the
digital audio program. If the two are different, it can result in audio playing
back faster or slower than expected.
For instance, let’s say that you have recorded audio from an ADAT, with
both the ADAT and the digital audio program set to 44.1kHz. Later, you
play back the same audio - but the ADAT’s sample rate has been changed
to 48kHz. In this case, the 44.1kHz audio data will be played back at
48kHz, resulting in faster, higher-pitched playback. If you change the
ADAT’s sample rate back to 44.1kHz, that audio will play back normally
again.
When recording, it is even more important to make sure that the digital
audio program’s sample rate parameter matches the actual sample rate of
