Chapter 65: Lo-Fi
Lo-Fi is part of the D-Fi suite of plug-ins and
provides retro and down-processing effects in
TDM, RTAS, and AudioSuite formats. Features
include:
•Bit-rate reduction
•Sample rate reduction
• Soft clipping distortion and saturation
• Anti-aliasing filter
• Variable amplitude noise generator
Lo-Fi down-processes audio by reducing its
sample rate and bit resolution. It is ideal for em-
ulating the grungy quality of 8-bit samplers.
Lo-Fi can be used as either a real-time TDM or
RTAS plug-in or as a non-real-time AudioSuite
plug-in.
Purposely Degrading Audio
Contemporary music styles, especially hip-hop,
make extensive use of retro instruments and
processors such as vintage drum machines, sam-
plers, and analog synthesizers. The low bit-rate
resolutions and analog “grunge” of these devices
are an essential and much-desired part of their
sonic signatures. That is why Avid created D-Fi.
The D-Fi suite of plug-ins combines the best of
these instruments of the past with the flexibility
and reliability of the Pro Tools audio produc-
tion system. The result is a set of sound design
tools that let you create these retro sounds with-
out the trouble and expense of resampling audio
through 8-bit samplers or processing it through
analog synthesizers.
Lo-Fi Controls
Sample Rate
The Sample Rate slider adjusts an audio file’s
playback sample rate in fixed intervals from
700 Hz to 33 kHz in sessions with sample rates
of 44.1 kHz, 88.2 kHz, or 176.4 kHz; and from
731 Hz to 36 kHz in sessions with sample rates
of 48 kHz, 96 kHz, or 192 kHz. Reducing the
sample rate of an audio file has the effect of de-
grading its audio quality. The lower the sample
rate, the grungier the audio quality.
The multichannel TDM version of the Lo-Fi
plug-in is not supported at 192 kHz, use the
multi-mono TDM or RTAS version instead.
