For Instant Voice Cloning and Professional Voice Cloning, we accept a range of file types. We strongly recommend MP3 at 192kbps or above. **Recommended format** * MP3, 192kbps or higher **Recommended length** * Instant Voice Cloning: 1–2 minutes of good audio * Professional Voice Cloning: 30–180 minutes of good audio Uncompressed formats such as WAV usually do not improve clone quality, and they can cause problems with the upload process. Focus on recording quality instead: use a clean recording with no background noise, room reverb, or multiple speakers, at a consistent volume and tone, without long gaps of silence. For more information, see [Instant Voice Cloning (IVC)](/docs/eleven-creative/voices/voice-cloning/instant-voice-cloning) and [Professional Voice Cloning (PVC)](/docs/eleven-creative/voices/voice-cloning/professional-voice-cloning). > ElevenLabs provides APIs and SDKs for text to speech, voice cloning, speech to text, sound effects, voice isolator, voice changer, and conversational AI agents.
