SoniqTools is a free, browser-based collection of audio tools, containing 18 tools in total, aimed at general listeners, DJs, audiophiles, and music producers. Its core feature is that all processing is done locally in the browser, files never leave your device, and no upload, registration, or installation is required.
Purpose and positioning It is used to analyze, convert, edit, and optimize audio files, and is suitable for users who need to quickly check audio authenticity, convert formats, or do simple editing.
Main capabilities Analysis and inspection: detect upsampling, check spectrograms, dynamic range, clipping, and true bit depth; visualize frequency content over time with adjustable FFT, color schemes, and dB range; compare two audio files side by side, and identify upsampled, transcoded, or fake high-resolution files through difference overlays; read and inspect ID3 tags, cover art, codec information, and embedded metadata of any audio file; visualize the complete waveform with zoom, pan, and channel separation. Conversion: convert between WAV, AIFF, FLAC, MP3, OGG, and AAC; extract audio tracks from video files, supporting MP4, WebM, MOV, and more; resample audio to 44.1k, 48k, 88.2k, 96k, or 192k Hz with high-quality interpolation; convert between 16-bit, 24-bit, and 32-bit float with correct dithering. Editing and transformation: loop audio through crossfade, fade out, gap, or reverse transitions, with the number of times or target duration configurable; precisely trim by visually setting start and end points on the waveform; split audio by silence detection, time intervals, or manual markers; merge multiple audio files with smooth crossfade, fade out, or gap transitions; adjust volume, normalize loudness to a target LUFS, or apply peak normalization; add smooth fade-in and fade-out curves with adjustable duration and shape; reduce file size while preserving quality by re-encoding with optimized bitrate settings; convert mono to stereo, or downmix stereo to mono, with correct channel handling; generate sine, square, sawtooth, triangle, white noise, and pink noise at any frequency; create silent audio files of any duration, sample rate, and bit depth for padding or testing.
How to use Open the website in a browser to use it, with no need to upload files to a server, and no registration or installation.
Applicable scenarios Suitable for audiophiles to identify fake high-resolution audio, DJs to process loops and merges, producers to do format conversion and basic editing, and scenarios that require quickly generating test tones or silent files.
Limitations The information does not specify browser compatibility, file size limits, whether there are paid items, or AI-related features; these detailsare not currently provided.
