| Plain text without web or formatting noise | Text Cleaner | Removes selected URLs, email addresses, HTML, emoji, invisible characters, or extra spacing | Important symbols and contact details may be removed |
| A narration draft with more deliberate punctuation | Punctuation Enhancer | Applies deterministic punctuation and capitalization rules | Rules can misread names, dialogue, code, or specialist text |
| Spoken lines extracted from SRT or VTT | Subtitle Cleaner | Strips selected cue notation, labels, sounds, tags, and duplicates | SRT/VTT output uses placeholder timing and needs retiming |
| A structured creator or audiobook script | Script Formatter | Adds line breaks, planning markers, pauses, and an approximate duration | Labels are not speaker detection and may be read aloud |
| Multi-character dialogue, podcast, or video voice-over | Multi-Speaker TTS | Assigns distinct voices to characters, adjusts turn pauses, and stitches dialogue into one audio file with SRT | Requires clear speaker tags; non-English phonemization boundaries apply |
| TXT transcript or SRT/VTT captions | Audio to Text | Runs Whisper transcription with segment or optional word timing | Names, numbers, speakers, and timestamps need human review |
| A louder, level-consistent copy of a recording | Volume Booster | Measures peak and RMS, applies gain, and limits the output | Peak normalization is not LUFS loudness compliance |
| A cleaned recording with the background noise reduced | Noise Remover | Learns the noise floor from the quietest window and gates below it | Steady noise only — clicks and overlapping speech survive |
| A tempo or key change on a finished track | Tempo Changer | Phase-vocoder stretch that preserves pitch, or shifts it on request | Phase-vocoder artefacts appear on dense percussion |
| One file cut into the section you need | Audio Trimmer | Waveform selection with sample-accurate start and end points | Cuts need a short fade or they click |
| The tempo, key, and level of an unknown file | BPM & Key Finder | Onset-histogram tempo, chroma key estimation, and loudness facts | Tempo and key are estimates and can lock onto a subdivision |
| A file at a different sample rate or channel count | Audio Converter | Resamples, folds to mono or widens to stereo, then re-encodes | Linear resampling is not mastering grade; exports are WAV or MP3 only |
| Narration audio for a video timeline | YouTube Voice Generator | Turns a reviewed script into downloadable speech | It does not create video, clone a person, publish, or guarantee monetization |
| A resumable book with paragraph audio | Ebook to Audio | Parses supported files, stores a local bookshelf, and generates selected chapters | Scanned PDFs need OCR; storage and phonemization boundaries apply |
