I will be happy to consult on your audio design needs. The primary areas in which I can contribute include:

• Audio power amplifier design
• Analog signal processing
• Purpose-built audio test instruments and "black boxes"

In the area of audio power amplifiers, I have extensive experience with most of the common amplifier technologies, including:

• Power MOSFET
• Bipolar
• Integrated Circuit (e.g., LM3886)
• Vacuum Tube

Just contact me with your needs here at bob@cordellaudio.com.

I can perform a battery of measurements on your design, with my strongest capability in the area of power amplifier measurement. In many cases I can perform unusually sensitive conventional measurements and some unconventional measurements.

Some examples of distortion measurement capabilities include:

• Ultra-low distortion THD measurements with spectral analysis
• Ultra-sensitive twin-tone IM with spectral analysis
• Multitone Intermodulation Distortion (MIM)
• Transient Intermodulation Distortion (DIM-30, DIM-100)
• Phase Intermodulation Distortion (PIM)
• SMPTE IM distortion
• Interface Intermodulation Distortion (IIM)
• Twin Tone Output Interface Distortion
