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.
Generate pure audio tones with sine, square, sawtooth, and triangle waveforms. Create multiple oscillators, binaural beats, and export as WAV.
Audio files recorded at different times or on different devices often have wildly inconsistent volume levels. The Volume Normalizer analyzes your file and adjusts gain so the loudness lands at a consistent target. You can normalize to a peak level or use perceived-loudness normalization for more natural results across varied content.
Bring all speakers to a uniform loudness so listeners do not have to adjust volume between segments.
Normalize a collection of tracks from various albums so playback volume stays even in a playlist.
Meet platform loudness targets before uploading to streaming services or social media.
Peak normalization adjusts gain so the loudest sample hits a target ceiling. Loudness normalization uses perceptual models to match average perceived volume, which handles dynamic content more naturally.
Loudness normalization can push peaks above 0 dBFS if the audio has a wide dynamic range. Use a limiter or leave headroom to avoid clipping.
It applies a uniform gain change across all samples. No frequency content is altered, so quality is effectively preserved.
