|BURWEN BOBCAT TONE BALANCER
Unlike resonant graphic or parametric equalizers which are too difficult to set,
the 6 gradual-slope tone controls operate completely independently. Their
contributions add directly in dB, and they cover a huge range of more than +/-
70 dB at 15 Hz and 20 kHz, all in fine steps of 0.1 dB. High frequency
reverberation choices: EXTREME, RECITAL, BASIC, and OFF really bring out
the spirit and feeling of your music tracks.
The program consists of two parts. BURWEN BOBCAT TONE BALANCER.xls
is a Microsoft Office Excel workbook that calculates filter coefficients from its
tone slider settings and high frequency reverberation selections. Excel sends
new filter coefficients to BURWEN BOBCAT TR which is the digital signal
processing part and included with BBTB.xls. You can set the sound via either
BBTR’s Pure Bobcat, Smooth Bobcat, or No Bobcat buttons or click the Process
Audio button in the Tone Balancer screen.
BBTR plugs into the Windows Media Player. It adds patented high frequency reverberation that produces ambiance
without echo. Unlike other artificial reverberation or real room reverberation that rolls off typically at frequencies above
2000 Hz, Bobcat’s greatest effect is above 10,000 Hz. The most important result from the addition and subtraction of
many sound reflections is thousands of peaks and valleys in the frequency response that make your music clearer,
cleaner, more musical, and easier to listen to. In addition an immediate overshoot in the reverberation decay curve
clarifies percussive sounds, somewhat akin to sharpening edges in a photograph. Think of BURWEN BOBCAT TR as
the final polish on your music product.
|HOW A MUSICIAN CAN USE BURWEN BOBCAT PRODUCTS
|APPLY BOBCAT TO YOUR PRODUCT
The simplest way is to use BURWEN BOBCAT TR’s high-speed file converter. In Windows Explorer just pick up your final edited stereo WAV, WMA, or
MP3 file and drop it on the Bobcat window after selecting Pure Bobcat or Smooth Bobcat processing. It will ask you whether to output WMA Lossless or
MP3 at 128 kbps and in what destination folder to place the 16-bit output file. If the input file is WAV 44.1 kHz, 48 kHz, or 88.2 kHz at 24 bits, the output
WMA Lossless file will have the same sample rate and 24 bits. If necessary, your editor or other file converter program can convert the output file to other
formats. Bobcat processing becomes part of the original sound and persists through any subsequent processing or conversion.
Normally BBTR is used for listening to edited tracks played by the Windows Media Player and converted to analog by the computer’s sound card. In
addition, if the Bobcat window is open, it will add its processing when ripping, or burning CDs. Running the free Line Input program from Chronotron
enables feeding WMP from your live performance mixer to produce processed analog output in real time.
When you set the sliders nothing happens until you click Process Audio. Changing the sound calculates 1,400,000 long formulas and your computer is
nowhere near fast enough for real time operation. The sudden change is an advantage. You can more easily discern small differences that fine tune
BALANCE YOUR SOUND PERFECTLY
BBTB is designed for listening. Operate the sliders to obtain the sound you like. Then make fine adjustments to zero in on that perfect balance. For
nearly optimized sound the last 0.1 dB becomes audible and important, especially in the ranges of the Middle and Treble controls. Refer to Tips on Tone.
Once you have attained the best possible sound from your edited track, you can create a music file having the new sound. If the only processing selected
is Pure Bobcat or Smooth Bobcat in BURWEN BOBCAT TR, you can apply the sound to an output file via its high speed file converter as above. To
include the new sound from BURWEN BOBCAT TONE BALANCER.XLS use a WMP plug-in that records the signal going from WMP to your sound card,
such as Total Recorder from High Criteria or the free WAV Output from Chronotron
The method above will work with Tone Balancer sound which substitutes for BBTR’s buttons.
If you use a MOTU 828MK3 8-channel Audio Interface for your sound card, you can produce up to 7 analog output channels from ordinary stereo files
that WMP can play. BBTB adds ambiance to all the channels for smooth room-filling sound with the instruments still up front where they belong. Its 43
position mix switch in combination with the 3 selections of high frequency reverberation provides a variety of environments. See BBTB’s Instructions.
For the ultimate in flexibility and perfection for either remasteing or live performance use Burwen Technology, Inc.’s AUDIO SPLENDOR. This software
from which BBTB and BBTR are directly derived has the tone control and mixing power of a 310 slider console with 313 buttons for selection of high
frequency reverberation. It accepts 1 to 8 channels in from which it delivers 1 to 7.1 channels out. All settings can be saved in and recalled from libraries,
or your entire system setup can be automatically reproduced when you click on a track in WMP.
AUDIO SPLENDOR operates as a DirectX plug-in for your audio editor, or as a plug-in for the Windows Media Player, or via its own 1 to 8 channel
Burwen Recorder-Player. Despite its extreme capability, it is very easy to use.
