Wav-File Recording
The XL2 records a wav-file of the measured input signal and
stores it on the SD Card. The available formats are:
Compressed• (default, using ADPCM compression). A new
wav-file is started automatically after 12 hours of recording
(typical maximum wav-file size = 512 MByte)
Compressed+AGC• , compressed with automated gain con-
trol. The gain control increases the level of low-level signals,
so that the wav-file is well-leveled during playback on the
PC.
24Bit_48kHz• , linear wav-file logging in 24 bit, 48kHz resolu-
tion with the optional Extended Acoustic Pack. A new wav-
file is started automatically after 1 hour of recording (typical
maximum wav-file size = 512 MByte)
Broadcast Wave Format BWF
The XL2 stores scaling factor, serial number,
date, time and time zone within the wav-file (ac-
cording to EBU TECH 3285). This information is
available through professional audio/video tools
typically used in broadcast.
