This  drawer  contains  two  demo  recordings  for the DSP enviroment.
Material  is packed into DPCM 4bit format to reduce space requirements
(please note that this format reduces quality too).

Unpack  the  files to AIFF16 (using the I/O Mapper tools) before using
the DSP.



DEMO: Hum.DPCM -------------------------------------------------------

This  file  contains an electric guitar recording affected by 50Hz hum
noise.   During  the recording operation, we used a defective cable to
raise the level of the hum.

The  'Hum  Remover'  DSP  operator  is  used  to  reduce hum affecting
electric devices (guitars, basses, microphones,...)


Set this recording as the source into the DSP enviroment.
Select the 'Hum Remover' operator.
Set  'Hum' to 50Hz (the frequency used by the electric company here in
Italy).
Set 'Remove' to 100% (remove the hum completely).
Click on 'Source/Play' to hear the original, deteriorated, signal.
Click on 'Execute' to hear the restored signal.

When  processing your own recordings set the 'Hum' gadget depending on
the frequency used in the country where the material was recorded.



DEMO: Gate.DPCM ------------------------------------------------------

This   file   contains  an  electronic  beep  recording,  affected  by
background   noise.    During  the  recording  operation,  we  used  a
low-quality analog tape to raise the level of the background noise.

The  'Noise  Gate' DSP operator is used to reduce the background noise
affecting signal pauses.

Set this recording as the source into the DSP enviroment.
Select the 'Noise Gate' operator.
Set 'Attack Time' to 10ms.
Set 'Threshold' to 90%.
Click on 'Source/Play' to hear the original, deteriorated, signal.
Click on 'Execute' to hear the restored signal.
