Convert text to speech using browser Web Speech API. Choose from multiple voices, adjust speed and pitch, and play audio directly.
Generate beautiful waveform visualizations from audio files. Choose from bars, mirror, line, or circular styles. Customize colors and export as PNG.
Automatically detect and mark silent sections in audio files. Visual waveform with highlighted silence regions. Remove all silences at once or export individual segments.
A noise gate monitors audio level in real time and mutes the signal whenever it falls below a threshold you set. This eliminates low-level background noise — fan hum, room tone, keyboard clicks — during pauses in speech or between musical phrases. Set the threshold, attack, hold, and release times, and the gate opens only when the signal is loud enough to matter.
The gate compares the incoming signal level to your threshold. When the level rises above it, the gate opens with the attack time you specify, letting audio through. It stays open for the hold duration after the signal drops, then closes over the release period. Short attack times catch quick transients; longer release times let natural reverb tails fade out instead of cutting abruptly. The range control determines how much attenuation the gate applies when closed — full muting or just a gentle reduction.
Mute background noise during pauses so only the speaker is heard.
Gate individual drum microphones to reduce bleed from other kit pieces.
Keep your microphone silent when you are not speaking to avoid transmitting room noise.
Remove air conditioning hum and ambient sounds between lines of narration.
Play back a silent section and watch the level meter. Set the threshold just above that reading so the gate closes during silence but opens when you speak.
No. A gate only acts when the signal is below the threshold. For noise that is present while you are speaking, use a noise reduction or spectral subtraction tool instead.
For speech, try 1-5 ms attack and 50-100 ms release. For music, longer release times (100-300 ms) tend to sound more natural.
