Estim Audio Generator 💎

Let’s walk through creating a simple "Throb & Tickle" file using Audacity. This will be a 60-second stereo file safe for beginners.

Several software tools are available for generating or managing e-stim audio signals: E-Stim Propack 2B Estim Digital Power Box estim audio generator

| Parameter | Safe Range | Notes | |-----------|------------|-------| | Frequency | 20–300 Hz | Below 20 Hz feels painful (DC-like). Above 300 Hz feels like buzzing. | | Amplitude | 0–50 V peak-to-peak after transformer | Depends on electrode area. Start low. | | Current | < 10 mA rms typical | Limit with series resistor. | | Waveform | Sine, square, triangle, or custom | Square waves give sharper sensation. | | Pulse width | 50–300 µs (if pulsed) | Common in TENS devices. | Let’s walk through creating a simple "Throb &

: Note the peak volume or normalization level (e.g., "Normalized to -3dB to prevent clipping"). Above 300 Hz feels like buzzing

: Usually a Class-AB or Class-D amplifier boosts the signal to a level capable of overcoming skin impedance (typically 1k Ωcap omega Ωcap omega Safety Mechanisms
