Start with the output you need
To create melodies from drawings, choose Draw Music Online. Audio to Text gets words from a recording; Text to Speech reads a script aloud. Audio Cutter keeps a section; the two converters prepare files for your next player or editor.
Choose a tool for your task
| What do you need? | Tool and action | What to check |
|---|---|---|
| Turn an image into a melody | Image to Music Choose a JPG/PNG/WebP and a color, brightness or layout mapping, then adjust the scale and listen. |
Inspect the notes and export WAV/MIDI or JSON for Draw Music. This maps pixels rather than recognizing emotions or generating AI vocals. |
| Draw a new melody | Draw Music Online Choose a voice color, draw on the canvas, then change key, scale and BPM. No input audio file is needed. |
Listen to the loop and export WAV for audio, MIDI for editing notes or JSON to reopen the drawing. |
| Get text from speech | Audio to Text Choose a file or record with the microphone, select a language and transcribe. Edit the text for copying or TXT; use SRT/VTT when you need timestamps. |
Compare names, numbers and unclear passages with the recording. Subtitles use the original recognition segments; see the troubleshooting section for editing details. |
| Generate Vietnamese speech | Text to Speech Paste a script or import TXT/MD, up to 1,200 characters per run. Choose a voice and speed, preview a sample, then generate the full text and download WAV. |
The sample reads only the beginning, up to 180 characters. After generating the full text, review names, numbers and punctuation in the WAV file. |
| Keep a section of a recording | Audio Cutter Select start and end points on the waveform or enter times. Export the current range, or add non-overlapping ranges for separate files in a ZIP. |
Listen at both cut points to avoid cutting off words. The ZIP contains separate clips; it does not join them into one recording. |
| Prepare a format for the destination | Convert to MP3 Audio Format Converter For MP3, choose a bitrate. For WAV, FLAC or another output, use the format converter and select an available format, sample rate and channel count. |
Open the file in your next application. Bitrate is data per second; changing formats does not guarantee a smaller file. WAV/FLAC do not use the bitrate setting. |
Connect steps for recordings and voice audio
From a script to a voiceover file
Split a long script into sections within the input limit and generate WAV for each section with your chosen voice and speed. If the destination needs MP3, convert the generated WAV and test it in the intended player.
Prepare an excerpt to share
Select the part of a song or recording you need, set cut points and export a format accepted by the destination directly in Audio Cutter. Convert again only when you need different settings; check the duration and play the final file.
If the result is not what you expected
- A file will not open or an output is disabled
- Reading and export support depend on the format inside the file and the browser. Renaming a file extension does not convert audio. Choose an available output; for an unreadable input, try WAV or MP3 exported by an application that can open the original.
- Model loading or microphone recording fails
- Transcription and speech generation need to download AI resources, especially on first use. Keep the connection and tab open while loading. For the microphone, check site and device permissions; if permission is unavailable, choose an existing recording file.
- Edited text does not appear in SRT/VTT
- The edited text is used for copying and TXT. SRT/VTT still export the original recognized segments and timestamps. To change subtitles, download SRT/VTT and edit the cues and timings in a subtitle editor.
- A large file or many clips fail to process
- Check file and duration limits at the input area; try a shorter sample or fewer export clips. Close unnecessary tabs and keep the page open until the download finishes.
Keep originals and manage drafts
Keep the original and listen to the result before sharing or using it in a project, especially cut points, names and spoken passages. Review AI transcripts and generated speech; converting to MP3 cannot restore detail missing from the source.
Audio and text processing run in the browser; resources and AI models still download over the network. Text to Speech and Draw Music Online save drafts and settings in browser storage. Use Clear on shared devices; download results or export the JSON project before clearing site data.
FAQ
Frequently asked questions about Audio Tools
What to know about cost, file counts and using a small screen.
Need more help?
Send the tool name, file format and a description of the issue so the KitoTool team can help.
Contact usAre these audio tools free?
Yes. KitoTool tools are free to use. File size, duration and text length limits vary by tool; read the input notice before starting.
Can I process multiple audio files at once?
File-based tools in this collection handle one source per run. Audio Cutter can export several ranges from that source in a ZIP of separate clips; this is not batch processing of multiple files or joining recordings.
Can I use the tools on a phone?
The directory offers search and filters on small screens; use the file picker in each tool. Audio reading, export and AI support depend on the browser, memory and device. Try a short sample first; guidance tables can scroll sideways.
