SpectraFoo Complete Additional Features
SpectraFoo has been designed to provide all of the tools you need
for a powerful suite of digital meters, with all of the
resolution of hardware meters at a fraction of the price. With
more than 15 individual metering tools, SpectraFoo gives you all
of the information you need to analyze and prepare your audio,
for production, performance, mastering, or broadcast.
SpectraFoo Complete was created for live sound engineers and
mixing engineers. Including tools to measure your acoustic
environment or verify the behavior of your external digital
devices, SpectraFoo Complete provides the following additions to
SpectraFoo:
Code-Level Metering
Three different kinds of bit meters for monitoring the low
level audio bitstreams
Bit Range Meter
Displays the range of sample codes exercised in the assigned
channel of each time slice. It shows the activity in each bit of
the sample word and shows you which bits are being exercised.
Bit Scope
Displays a list of the codes of all of the samples in the time
slice. This allows you to see low-level activity in the signal,
stuck bits, DC offsets and the like.
Each time the display is updated, all of the sample in the time
slice are shown. The number of samples in the time slice are
determined by the I/O hardware's buffer size. The samples are
displayed starting with the first sample in the time-slice in the
upper left hand corner of the instrument. Each successive sample
is place under the previous one until the bottom of the column is
reached. The next sample is placed at the top of the next
column.
Bit Matrix Meter Instantaneous Snapshot
Pinpoint problems with processing algorithms in your data
stream, and test and design DSP algorithms with this
comprehensive readout.
The Bit Matrix Meter is designed to work with 16-bit delivery
media and only utilizes the top 16 bits of the samples in the
signal. The meter takes the 16-bit samples and divides them into
two groups: the most significant byte (MSB) which is the top 8
bits, and the least significant byte (LSB) which is the bottom 8
bits. For each sample these groups are then converted to
horizontal (MSB) and vertical (LSB) offsets into a 256x256 pixel
matrix.
Bit Matrix Meter Accumulation Snapshot
Switch the Bit Matrix Meter into Accumulation Mode and display
the aggregate utilization of the code space. The accumulation
mode does not erase the bit matrix with each new time-slice and
this accumulates a picture of all of the sample code that have
been exercised by the signal. This snapshot shows us that while
most of the codespace is exercised by the signal, the top 3dB or
so is pretty sparse. This indicates that we could compress this
signal with a pretty hard ratio and a 3dB threshold and introduce
very little distortion.
Full featured world-class signal
generator
SpectraFoo Complete now has a high-resolution multi-tone,
multi-noise, sweepable, burstable signal generator. The generator
is capable of running in real-time, or alternatively striping
signal into a capture or into an AIFF or SDII file. The interface
to the signal generator is numerical, which makes it very
precise,
- Provides high resolution 24-bit distortion free signal
generation
- Up to 9 simultaneous sine sweeps
- Pink and White noise generation
- Burst Generation
- FFT synchronized sine generation
- Direct generation to audio I/O, captures and files
Transfer Function Measurement System
For live sound, equipment testing, or any application where
you need to analyze the characteristics of acoustical and
electrical audio systems, SpectraFoo Complete's built in
transfer function display shows you the relative power and phase
response between the left and right channels. Using Metric
Halo's Music Based Measurement™, the source signal is
the input to some audio processing arrangement and the response
signal is the measured output of the system, making music your
"test tone". SpectraFoo uses the source signal as a
point of reference and the transfer function display shows the
differences in amplitude and phase between the source and
response as function of frequency.
This allows you to measure the properties of audio processing
systems, including systems that contain acoustic elements. You
can determine the amplitude and phase response of an equalizer in
the presence of musical signal as easily as measuring the sound
coloration of an acoustic space.
SpectraFoo provides a Delay Detection Feature to properly
measure the power and phase of the response signal relative to
the source signal, as the source signal must be delayed to
time-align it with the response signal. The delay finder records
a segment of both signals and computes the correlation of the
signals with each other. By moving the cursor to the largest
correlation of the two signals, you set the system delay and
compensate for the measurement delay, time-aligning the two
signals.
Capture and Static Analysis system
- Allows you to record directly into SpectraFoo's RAM based
capture system
- Provides loop playback
- Allows you to open sound files for detailed analysis
When Data Slicing is enabled, the realtime instruments display
the data which lies underneath the current position of the
cursor. If you drag the cursor around in the overview window, the
realtime instruments will continuously update to reflect the
current cursor position. If you replay the capture, the realtime
rack will continuously update in sync with the playback.
Audio professionals are using SpectraFoo every day to solve real
world problems. Whether you have to match the EQ of two different
tracks, analyze a synthetic sound to match an original sample, or
tune a room, SpectraFoo will help you get it done faster and
better. You can use Foo in tracking, recording, mixing and
mastering sessions as well as during the setup and mixing of live
shows.
