Files: Estim Wav

The best files do not start at 100%. They begin with a low-amplitude, low-frequency "thump" to let the skin acclimate and the conductive gel to settle. A ramp might last 30 seconds to 2 minutes.

This is the "roller coaster" of estim. The file slowly sweeps from low frequencies (thud) up to high frequencies (buzz) and back down. This moves the sensation from deep tissue to surface nerve endings, preventing numbness. Estim Wav Files

If a Wav file is poorly made, it may have a constant voltage level (DC offset). This burns your skin and feels like a hot needle. Use audio software like Audacity (free) to view the file. The waveform should cross the center line (0) regularly. If it sits entirely above or below, do not use it. The best files do not start at 100%

While any .wav file can technically play through an e-stim box, optimized files adhere to strict standards: This is the "roller coaster" of estim

| Parameter | Recommended Specification | Reason | | :--- | :--- | :--- | | Sample Rate | 44.1 kHz or 48 kHz | Prevents aliasing artifacts that cause erratic output. | | Bit Depth | 16-bit | Sufficient dynamic range for smooth intensity changes. | | Channels | 2 (Stereo) | Allows independent control of two output channels (e.g., Channel A / Channel B). | | Peak Amplitude | -0.1 dB to -1.0 dB (normalized) | Ensures full dynamic range without digital clipping, which can cause painful sharp spikes. | | DC Offset | 0.0 (AC-coupled) | Any DC voltage can cause electrolytic burns. High-quality stim files are AC-balanced. |

Before connecting to your body, listen to the WAV file through speakers.

A 5-minute Estim Wav file might have a gentle intro but a brutal 3-minute drop. Skip through the file at low volume first to identify "spikes."
