AI & Audio Processing Methods
Updated November 2026 · v11.1 · Site created, designed and developed by Eddie Boothby.
What AI means here
Caption Catcher includes an optional speech-recognition mode using a downloadable machine-learning model. Its other lyrics-assisted editing modes do not necessarily involve recognition. The other applications listed below are described according to their publicly visible signal-processing functions. Automation, presets, advanced analysis and the term “studio” do not by themselves mean artificial intelligence.
Features may be revised and specific implementations can depend on browser capabilities. Where the underlying source has not been independently audited, the descriptions below do not constitute a guarantee that no external libraries or model-based component will ever be used.
How each application processes your work
This inventory describes the general method and what the result can reasonably be used for. It intentionally does not expose proprietary source code, internal signal-chain parameters, security controls or private infrastructure.
| Application | Method and important limitations |
|---|---|
| Caption Catcher / Lyrics to SRT | Machine learning in optional speech-recognition mode Lyrics-assisted editing and timestamp adjustment use supplied text and timing controls. Optional speech recognition downloads a model and runs recognition in the browser through a WebAssembly-based library; loading model assets contacts an external delivery network. Confirm the selected mode before using sensitive audio. |
| Promo Video Studio | Conventional rendering and browser media APIs Audio visualization, timed text layers, animations and recording use browser graphics, audio analysis and supported media encoding. This does not require generative AI. |
| Loudness Meter | Signal measurement Computes loudness and peak-related measurements from decoded audio samples. Browser calculations and measurement approximations are not proof of platform certification. |
| ID3 Tagger | Metadata parsing and editing Reads and writes song metadata, artwork and tag fields. Optional metadata lookups, where enabled, may contact online catalog services. |
| BPM Finder | Rhythm/tempo analysis Estimates tempo using signal and beat-pattern analysis, with manual tap-tempo input. Suggested BPM values can be half- or double-time. |
| Audio Converter | Audio decoding, resampling and encoding Uses browser audio APIs and encoders; optional conversion modes may call server processing where implemented or needed. |
| Audio Fade | Waveform gain processing Applies amplitude envelopes over selected start and end intervals. |
| Audio Trimmer | Waveform editing Selects and exports part of a decoded audio recording, subject to supported encoding formats. |
| Batch Audio Processor | Batch signal processing Applies normalization to multiple audio files and creates downloadable outputs. |
| Mastering | Digital signal processing Adjusts frequency balance, dynamics, stereo width and output levels. Presets and targets are not automatic professional mastering guarantees. |
| Dynamic Master Pro | Multiband dynamics DSP Processes level and dynamics in multiple frequency bands; no trained model is claimed for the core processing. |
| Studio EQ Pro | Equalization DSP Applies filter-based tonal adjustments and displays audio analysis. |
| Vocal Studio | Signal processing and pitch analysis Uses vocal cleanup and monophonic pitch/scale adjustment; the feature description alone does not establish use of a trained AI model. |
| Noise Remover | Noise gate and signal cleanup Reduces quieter background noise using configurable signal thresholds, not a claimed generative AI cleanup engine. |
| Audio Restoration Studio | High-pass filtering and expansion Uses filtering and gate/expander processing; it is not represented as neural stem isolation. |
| Spectral Audio Repair | Time-frequency signal editing Displays a spectrogram and allows targeted frequency-region changes or hum cleanup. |
| Clip Fixer | Sample interpolation Attempts to repair brief clipped audio sections with sample interpolation; severely clipped recordings cannot be guaranteed to recover. |
| Stereo Imaging Studio | Mid-side DSP Changes stereo width and enables mono compatibility monitoring. |
| PhaseLab Stereo Scope | Phase and correlation analysis Measures channel relationships and possible mono-cancellation risk. |
| PulseForge Transient Designer | Envelope/transient processing Adjusts attack and sustain characteristics using audio signal processing. |
| SubForge Bass Architect | Low-frequency DSP Shapes sub-bass, harmonics and low-frequency stereo characteristics. |
| Stem Splitter | Frequency and stereo-position filtering, not AI source separation Creates frequency/position-based tracks; they are not guaranteed isolated vocals, drums or instruments. |
| Copyright Evidence Checker | Audio comparison and metadata research Provides comparison signals and supporting catalog checks; some lookups can contact external music metadata providers. It cannot determine copyright ownership or provide legal clearance. |
| Streaming Readiness Audit | Signal measurement and reporting Reviews loudness, peaks, silence and phase indicators; findings are estimates, not proof of acceptance by streaming platforms. |
| Music Release QC | Basic audio quality measurements Checks sample peaks, silence, RMS and sample-rate information; it is not a distribution certification. |
| DJ Track Preparation | Tempo and cue estimation Estimates BPM, activity regions and DJ cue-grid points; verify beat grids before performances. |
| Reference Match Studio | Comparative measurements Compares levels, dynamics and stereo properties of a target and a reference file; it is not a neural style-transfer service. |
Browser processing, network requests and saved projects
Many audio operations run on audio data decoded and processed in your browser. Loading JavaScript libraries, fonts or speech recognition model files may still make requests to third-party hosts, which may receive IP address and standard connection information. Optional server-assisted conversion, saved projects, accounts, forms or online music catalog searches may transmit different information depending on the selected feature. Do not assume every operation is entirely offline or that every file is automatically uploaded to an external AI provider.
Temporary files and account data have different handling paths, and a uniform retention period has not been independently verified for every operation. Consult the Privacy Policy for data handling and contact options. For confidential recordings, verify the selected processing mode before proceeding.
Reliability and ownership
Recognition can miss or invent words; caption timestamps may be inaccurate. BPM can be detected at half or double tempo. Loudness and streaming checks are decision aids, not certification. Frequency-based stems are not guaranteed clean instrument separation. Music rights comparisons do not establish copyright ownership or license permission. Verify outputs before release or distribution.
