You can check the control on the LED displays in the recording dialog.
If the level is too high, reduce the incoming signal. If the recording source is
connected through the amplifier or tape deck’s line out connectors, then you
can reduce the incoming signal only by using the sound card’s mixer window.
This is located in the recording dialog under the "Level control" tab.
If you reduce the input sensibility with the sliding regulator (fader), then you
also reduce (with many sound cards) the precision of the resolution of the
digitized analog signal. This is why these controls should be kept at the loudest
possible setting!
The standard for optimal adjusting is naturally the loudest section of the
material. This should be turned to the maximum setting
Digital transfer
With the recording function, digital audio data can be transferred to the hard
drive through a digital interface (e.g. S/PDIF or ADAT).
ADAT or DAT recorders normally produce data with a sampling rate of 48 kHz.
For a CD project with 44.1 kHz you must convert the sampling rate. This is
carried out in real time by Samplitude 11.5 Producer. The digital signal is read
at 48 kHz, but is automatically converted and inserted into the project as an
audio file at 44.1 kHz.
For this to occur correctly, you must first set the sample rate of the incoming
signal in the recording dialog. Click on the "Dev." button in the recording
dialog. In the following dialog (sound card characteristics), set the audio
recording formats supported by the sound card.
Now, connect the digital output of your recorder to the digital input of your
sound card, and now start recording!
24-bit audio support
Audio files in Samplitude 11.5 Producer can not only be recorded in 16-bit
quality, but also in far superior 24-bit resolution. Simply click the ”device”
button in the recording dialog, and select the ”24-bit” option under ”sound
card properties”. 24-bit recordings require a high-quality audio card with 20 or
24-bit converters, as well as a 24-bit-compatible NME drive. 24-bit audio
material can also be transmitted via audio cards with SPDIF digital interfaces.
We have had positive experiences with the 24-bit audio cards produced by
Marian, RME, SEKD and Terratec.
