Free Online Audio Equalizer: Shape Your Sound
Welcome to our professional 10-Band Graphic Equalizer. Have a song that lacks bass? Or maybe a voice recording where the background noise is too sharp? An equalizer (EQ) is the ultimate tool to sculpt your audio by adjusting specific frequency ranges without altering the whole track.
Understanding the Frequencies
Our equalizer splits the human hearing spectrum into 10 distinct bands. By moving the sliders up (boosting) or down (cutting), you change the volume of that specific frequency.
- Bass (32Hz - 125Hz): These are the low, rumbling frequencies. Boosting these will give your music a heavier, club-like feel (Sub-bass and Kick drums).
- Mid-Range (250Hz - 2kHz): The core of the audio. This is where most human vocals, guitars, and pianos sit. Adjusting these can bring a singer to the front of a song.
- Treble (4kHz - 16kHz): The high, crisp frequencies. Boosting treble adds clarity and 'air' to the sound (like cymbals or crisp pronunciation), but too much can sound harsh.
Secure In-Browser Processing
Like all tools on VoiceRecorder.in, your privacy is guaranteed. The audio equalization uses the Web Audio API's BiquadFilterNode directly on your device. We never upload your music or private recordings to our servers. Processing is instant and unlimited.
