AUDIONET - Scientific magic.
Audionet CARMA 4

Short Description

Audio files to create an audio CD with external measurement signals for mono-, stereo- (up to 2.2), multichannel- (up to 7.1) and separate subwoofer-measurements.

Preparation:

Burn the 16 Files in the subfolder as Audio-CD. Make sure that these measurement signals are stored on the CD without any manipulation. No normalization or volume correction may be activated on your burning software.

Note

On performing 5.1, 7.1 or Sub (DTS) measurements with the Audionet Test Signal CD the subwoofer is driven by the LFE channel of your surround pre-amplifier (like Audionet MAP I or MAP V2). Following the Dolby and DTS specifications this LFE channel is mixed and recorded with -10dB level. Hence all Dolby Digital and DTS 5.1 processors automatically add 10dB to the LFE output channel to achieve the correct channel balance between main channels and LFE channel. This is not respected by CARMA and its external test signals! So if your subwoofer is calibrated correctly it must show a +10dB higher level compared to all other channels.

Important Note

It is not recommended to use and playback the measurement signals via a computer parallel to CARMA or via a NAS, rather you have to perform the playback from a CD, DVD or Blu-Ray player. We advise against the playback by an audio-software (like Foobar, Winamp, Mediaplayer) due to different sources of error (re-sampling, software equalization etc). Exact measurement results can’t be guaranteed by this way of use.
