stute.x1A PC Audio Analyzer

Precise electrical & acoustical measurements up to 90kHz!

Measurements up to 90kHz@192k sample rate

Find the best speaker driver transmission range.

Check the audio Filter behavior (Cutoff frequency...)

Test your audio filter impedance EQ-circuit (RC/RLC)

Verify the bass reflex port tuning. IDENTIFY AND IMPROVE SOUND ERRORS

Test your audio amplifier or TONE/EQUALIZER CONTROL function

Measure the driver thiele small parameter (Vas, qts,...)

Analyze the signal distortion (k2..k7)

Application samples

Measurement frequency response acoustic

Check speaker driver or a loudspeaker box

Audio filter check

Verify the cutoff frequencies and slope or measure the driver impedance influence to the filter characteristic.

FFT acoustic

Spectral analysis of the signal response from speaker driver or loudspeaker box

Measurement frequency response electrical

Check amplifier, tone control, EQ, microphone amplifier,...

FFT electric

Spectral analysis of the signal response from a power amplifier or pre-amplifier

Speaker driver Thiele Small Parameter (TS)

The driver TS parameter measurement like Vas or Qts. Export to stute.x1D Designer

Signal distortion

Measure the acoustical and electrical signal distortion. Get the harmonics k2..k7.

Z measurement

Driver impedance Z measurement to get the best input for the audio filter calculation. Also verification of the impedance EQ circuit (RC / RLC) or the bass reflex tuning.

System requirements

A Computer with MS-Windows 7, 8, 10 (32 & 64 bit). Processor i3 1.5GHz or above, screen resolution min. 1024x768 pixel. Internet connection to activate the license.

A Commercial USB Audio interface with headphone output, stereo line input and microphone input. Level of inputs and outputs must be adjustable at the audio interface per gain control knob. Supported driver ASIO or Windows WDM. Sample rate 44.1kHz, 48kHz, 96kHz, 176.4kHz, 192kHz.

The simple interface stute.x1S for electrical / Z measurement. Only acoustical measurements are without stute.x1S possible.
