Voice notes and recordings come in formats that not every player or upload form accepts. OPUS to MP3 converts WhatsApp voice notes, M4A to MP3 handles iPhone recordings, and the audio converter covers WAV, FLAC, OGG and more. To keep only the sound of a video, use video to MP3.
To edit, cut a section out of a track, make a 30-second ringtone, or raise the volume of a quiet recording. Record straight from the microphone with the voice recorder, and turn speech into text with audio to text, which runs a Whisper speech-recognition model on your device.
