High Performance Analysis

Low cost audio analysis instrument for stand-alone measurements or data collection via PC

Key Features

  • Studio grade measurements

  • Stand-alone operation / PC analysis tool

  • Fast measurements down to 120 ms per point

  • 4096 point FFT and 240 point sweeps

Broad Functionality

DMME Audio Analyzer runs highly optimized embedded code to quickly measure multiple audio signal metrics at once

Using the well respected PCM3060 I2S audio codec, it delivers studio-grade measurements and analysis features for hobbyists and professionals alike

  • Signal level measurements

    • Vrms

    • Vp-p

    • dBu

  • Noise and distortion

    • SNR

    • THD

    • THD+N

    • SINAD

  • Frequency sweeps

    • Bode plots

    • THD vs. Frequency

  • Amplitude sweeps | transfer curves

  • Frequency measurement | detection

  • 4096 point FFT | spectral analysis

  • Waveform capture and visualization

A rare combination: low-cost, fully self-contained audio analyzer and signal generator for true stand-alone operation — no external equipment required.

“The one and only stand-alone audio analyzer without breaking the bank“

Easy Calibration

Pre-calibrated using a 16-bit source (AWG) for both -10dBV and +4dBu ranges

Easily re-calibrate analyzer ADC with your own high performance external source

Self-calibration function for analyzer DAC

Loop-back connection (non-BNC version) when no cables connected for quick verification

PC Analysis & Captures

Supports PC analysis via USB serial and supporting software

Export data to CSV format and compare sweeps using the PC application

Simple Interface

Using a simple UI structure, there are no secret menus or controls that require reading an extensive manual

3.5” touch screen with 240x320 resolution for clear plots and data visualization
