What is an Audio to Text Converter?
You have an audio recording — maybe a podcast episode, an interview you conducted, a meeting recording from Zoom, a voice memo from your phone, a lecture capture, or even a phone call. An audio to text converter takes that recording and turns it into accurate, searchable written text. Unlike video URL tools, this is built specifically for audio files you already have on your device or in your cloud storage.
Audio quality directly affects transcription accuracy. Key factors include sampling rate (16kHz or higher recommended), bitrate (128kbps or above for speech), and encoding format. Our AI is optimized for real-world recordings — not just clean studio audio. Phone-quality recordings, conference room captures, and field interviews all produce usable transcripts, though cleaner audio always yields better results.
The range of audio you can transcribe is vast: from a quick 30-second voice memo on your phone to a 2-hour podcast episode, from a noisy café interview to a pristine studio recording. Our AI adapts to different audio conditions, automatically adjusting for background noise, varying volume levels, and multiple speakers to deliver the best possible transcript.
Supported Audio Formats
Upload any audio format — our AI handles the rest
MPEG Audio Layer 3
The most common audio format. Lossy compression preserves speech clarity well. Recommended at 128kbps or higher for best transcription accuracy.
Waveform Audio
Uncompressed lossless audio. Produces the highest transcription accuracy but larger file sizes. Ideal for professional recordings and archival quality.
MPEG-4 Audio
Apple's default recording format used by iPhone Voice Memos and GarageBand. AAC codec provides good quality at smaller file sizes than MP3.
Free Lossless Audio Codec
Lossless compression — studio quality without the huge file sizes of WAV. Popular among audiophiles and professional podcasters.
Ogg Vorbis
Open-source lossy format used by some recording apps and Linux systems. Good quality at low bitrates. Fully supported for transcription.

Recording Best Practices
Get the best transcription results by following these recording tips.
Microphone Placement
Position your microphone 6-12 inches from the speaker. For interviews, use separate microphones or a central recorder equidistant from all participants. Avoid placing mics near fans, air conditioners, or keyboards.
Environment Matters
Record in the quietest space available. Close windows, turn off appliances, and avoid rooms with hard surfaces that create echo. Even a small closet with clothes is better than a large empty room.
Recording App Settings
Use 44.1kHz sample rate and at least 128kbps bitrate. On iPhone, Voice Memos defaults to compressed quality — switch to Lossless in Settings for better accuracy. On Android, use a recorder app that supports WAV export.
Multi-Speaker Recordings
For meetings or interviews with 3+ people, use a conference microphone (like Jabra Speak) or ask each participant to record their own audio separately. Our AI handles mixed audio well, but clearer separation means better speaker labels.
