Prompt Minds has 9 free audio tools for musicians, students, teachers, podcasters and anyone who works with sound. Cut a song into a ringtone with fade-in and fade-out, convert between MP3, WAV, OGG and M4A, record your voice with a live waveform, have text read aloud in Hindi or English, type by speaking, or practise with an accurate online metronome. The audio tools run inside your browser, so your recordings and music files stay on your device.

What you can do with these audio tools

  • Edit: cut any part of an MP3, WAV, M4A or other audio file with a visual waveform and export it as MP3 or WAV.
  • Convert: change audio formats in batches — MP3, WAV, OGG (Opus) and M4A (AAC), with bitrate control.
  • MP4 and ringtones: wrap M4A or raw AAC audio in MP4 without re-encoding (or add a picture to make a YouTube-ready video), and make iPhone M4R ringtones of up to 40 seconds.
  • Record: capture voice notes, lectures or podcast takes from your microphone, then download them or save as MP3.
  • Speech: listen to any text with your device's Hindi and English voices, or dictate text with voice typing in Hindi, English and other Indian languages.
  • Practice: keep perfect time with a metronome from 30 to 300 BPM, with accents, time signatures and tap tempo.

Private by design — and honest about it

Cutting, converting, recording and the metronome run entirely in your browser; nothing is uploaded. Text to Speech uses the voices installed on your device. Voice typing is different: browsers such as Chrome and Edge send the audio to their own speech recognition service to turn it into text — Prompt Minds never receives it, and the tool page explains this clearly. Every tool works without an account, and each page lists its browser support and limits so you know what to expect.

Popular audio tasks

Want a custom ringtone? Cut the chorus with the Audio Cutter and add a short fade. Need a WAV for editing software or an MP3 for an old player? The Audio Converter handles whole folders at once. Recording a voice note or lecture? Use the Voice Recorder and download MP3. Writing in Hindi without a Hindi keyboard? Try voice typing.

Frequently Asked Questions

Are these audio tools free?

Yes. All audio tools on Prompt Minds are free, with no sign-up, no watermark and no limits.

Are my audio files uploaded?

No for cutting, converting, recording and the metronome — they run entirely in your browser. Voice typing uses your browser's speech service (for example Google in Chrome), which processes the audio to produce text; Prompt Minds does not receive it.

Can I make a ringtone?

Yes. Use the Audio Cutter to select up to 30–40 seconds of a song, add a fade-in and fade-out, and export it as MP3 for Android or convert it to M4A for other phones.

Does text to speech support Hindi?

Yes, when a Hindi voice is installed on your device or browser. Chrome, Edge, Android and many Windows and Mac systems include Hindi voices.

Do the audio tools work on mobile?

Most do. The Audio Cutter, Converter, Voice Recorder, Text to Speech and Metronome work in modern mobile browsers; voice typing works in Chrome on Android and in Safari on iPhone where supported.
