ToneScope vs Audio Toolbox

ToneScope helps you see and understand sound in real time. ToneScope transforms complex audio into visual representations that are easy to interpret. Whether you're exploring music, investigating environmental noise, or simply curious about the sounds around you, ToneScope makes sound easier to understand. It uses a multirate FFT approach to achieve high frequency resolution at low frequencies while remaining efficient for real-time use on iOS. Users can analyze audio in real time or record sound locally and analyze it later. All processing is performed entirely on-device. Optional audio recordings are saved locally under user control. No data is transmitted, uploaded, or collected. Designed and developed by Newton Niu.

Audio Toolbox brings practical audio workflows together in one private, easy-to-use app. Convert compatible audio to M4A/AAC, WAV, AIFF, CAF, or ALAC. Extract sound from MOV and MP4 videos. Make an audio file smaller with quality presets or fit it under a specific file-size limit. Trim with a real waveform, combine tracks in the order you choose, and process batches without uploading your recordings. Everything happens on your iPhone: - No account - No uploads - No advertising - No tracking - Originals are never modified Free tools include conversion, basic video-to-audio, trim, compression, and batches of up to five files. Audio Toolbox Pro is a single lifetime purchase that unlocks target-size compression, merge, unlimited batch processing, advanced controls, and advanced output formats. Supported input includes compatible AAC, M4A, MP3, WAV, AIFF, CAF, ALAC, FLAC, MOV, and MP4 files. Output includes M4A/AAC, WAV, AIFF, CAF, and ALAC. Compatibility depends on the actual media track, not only the file extension. Protected media cannot be processed.
