  Professional audio processing on a PC



   Once I got to thinking: Is it possible on the PC to make 
processing of sound at a level close to a professional. In some 
magazine I read that on the PC software

there is not that, they say, and it appears not yet
soon. Desperate, I and nothing on
counted.

   But once, on a pirate CD, I found
ruleznuyu veshchichki called Sound Forge
4.0c + Plugin's. In the program a lot of effects
and functions that are needed for professional work with sound. 
It is worth noting, intuitive user interface, mapping of the 
processes occurring on the screen. Program Sound Forge supports 
large number of different audio file formats and can use a 
variety of audio compression algorithms. The program works 
without problems with large audio files.


What can Sound Forge??? Let us together
look:

1. Reverb and chorus, modern life is not
possible without these two effects ;-).

2. Compression and stretching of the sound (with no impact on 
its altitude). Not bad, not true!


3. Changing the pitch.

4. Equalizers (2 types, one can easily
give the desired sound tonal coloration).

5. Dynamic processing (using a dynamic processing, you can 
narrow or expand the dynamic range of the signal to limit the 
audio level, remove noise, lying below a specified level, there 
is a dynamic multi-band filter). 

6. Funds for restoration and cleaning of phonograms (remove 
unwanted noise from sound files => possibility of the 
restoration old phonograms).


7. Spectral analysis (lets see
spectral picture of the entire file or selected area sound 
waves). 

8. Lots of special effects.

9. Sound synthesis (allows you to get complicated
sound effects, or imitate sounds
analog synthesizer).

10. Editing samples.


   One of the strengths of the Sound Forge - it sounds great 
editing capabilities for further use in samplers. The 
composition includes Sound Forge Loop Tuner - a tool for 
creating and special editing samples.


   This technique (looping) allows
achieve an arbitrarily long playing short sounds in sampler. To
start editing using Loop
Tuner, you must first select a mouse that
part of your sample, you want to turn into a loop, and execute 
Special / Edit Sample. Then, in the auxiliary menu that 
appears, you need to put a mark in titles Sustaining (or 
Sustaining with Release), Infinite Loop and click OK. Now you 
can use the tool itself Loop Tuner command View / Loop Tuner. In

top window shows all your recorded track in full, and the 
bottom you see in maximizing the place, "joint" beginning and 
end of the allocation. Our challenge now is how to

precisely fit the "gluing room" for one
other. Actually needed to end a wave of
the chosen area (left half
the bottom window) is like a natural
continuation of the wave it began. Initial and
end points of the cycle can be easily moved from
using the available means of control: it is possible
move both points at once, pre-
fixing the length of a looped section
button.

Conclusion:
^^^^^



   Anyone, having spent little money can equip themselves with
home audio studio, and get with the help of audio production is 
quite professional quality. Audio processing on the computer 
has a huge advantage over traditional, using analog tape 
recorders, mixers and other expensive and bulky equipment, 
which houses post impossible. Such equipment costs tens of 
times more music studio based on the computer.
