Hi,
First use of a PCM92.
What settings to use to distort a voice? It will be used to anonymize a voice.
Anyone has used this before for this purpose?
Best regards
Chris

Hello,
The Lexicon PCM92 is a powerful reverb and effects processor, but it's not ideal for primary voice anonymization. Here's why:
Limited Anonymization: While distortion can obscure the voice slightly, a skilled listener might still recognize it.
Focus on Effects: The PCM92 excels at studio-quality reverbs, delays, and other creative effects. Voice anonymization requires specialized tools.
Here are better options for voice anonymization:
Software Tools: Dedicated software like Audacity or Adobe Audition offer pitch shifting, noise shaping, and other anonymization effects.
Online Services: Some online services (use with caution regarding privacy) offer voice anonymization features.
Alternatives for the PCM92:
If you still want to use the PCM92 for creative voice alteration, here are some settings to try (experimentation is key):
Pitch Shifting: Use the "Multi-voice pitch shift" effect to significantly alter the voice's pitch.
Formant Shifting: Explore if the PCM92 allows formant shifting, which alters the vocal resonances for a more disguised sound.
Delay and Reverb: Combine these effects subtly to create a more distant and distorted voice.

The Lexicon PCM92 is primarily a high-quality digital reverb and effects processor rather than a device specifically designed for voice distortion or anonymization. However, with creative use of its features, you might achieve some interesting effects.
To distort or anonymize a voice using the PCM92, you could try the following approach:
Selection of Effects: Look for effects that can introduce significant modulation or pitch shifting. Effects like "Pitch Shift" or "Resonant Chords" might be useful.
Adjust Parameters: Experiment with the parameters of the selected effect. For instance, increase the modulation depth or pitch shift amount to distort the voice.
Feedback and Delay: Some delay effects can create interesting textures when applied to a voice. Experiment with delay times and feedback settings cautiously to avoid unwanted artifacts.
Reverb Effects: Although reverb is the PCM92's specialty, you might find that certain reverb algorithms with modulation can add a unique character to the voice.
EQ and Filters: Use EQ to shape the frequency response of the processed voice. Cutting or boosting specific frequencies can further obscure the original voice.
Trial and Error: Since the PCM92 is a versatile unit, much of the process will involve trial and error. Don't hesitate to try combinations of effects and settings to find what best suits your anonymization needs.
The Lexicon PCM92 is primarily known for its high-quality reverbs and effects rather than traditional voice distortion or anonymization effects. However, with creative use, you might achieve some interesting results. Here’s a general approach to try:
Selecting Effects: Explore the PCM92's modulation and pitch-shifting effects. These can introduce the type of alterations that might anonymize a voice by changing its pitch and timbre.
Pitch Shift: Use the pitch-shifting capabilities to alter the pitch of the voice. This can make it higher or lower, potentially masking the original voice.
Modulation Effects: Effects like chorus, flanger, or tremolo can add modulation to the voice, making it sound more processed and less recognizable.
Filtering: Experiment with EQ settings to emphasize or de-emphasize certain frequencies. Cutting specific frequencies might obscure the voice while still allowing it to be understood.
Reverb and Ambience: While reverb is the PCM92's forte, adding a subtle amount can help blend the processed voice and make it less distinguishable.
Delay Effects: Adding delay with short feedback can create a doubling effect, which might help in anonymizing the voice by making it less clear.
The PCM92, a digital effects processor by Lexicon, is well-known for its high-quality reverbs and effects, but it can also be used for tasks like voice distortion. If you’re looking to anonymize a voice by distorting it, you’ll want to use settings that effectively alter the voice while still being clear enough to be recognized as speech. mary kay intouch
