Enterprise customers using our most advanced model, Caruso, can now choose from multiple sample rates–giving you greater control over audio quality, performance, and file size to match your workflow.
What is a Sample Rate?
A sample rate determines how often audio is measured per second during rendering and playback. Higher sample rates produce better audio quality, but result in larger file sizes.
Note: Multiple sample rates are available only for voices using the Caruso model.
Available Sample Rates
| Sample Rate | Best For | File Size | Audio Quality |
| 24 kHz Lightweight and efficient for low-bandwidth use. | Voice notes, support tools, basic TTS | Small | Good |
| 48 kHz Balanced and standard for most media and platforms. | Video playback, web apps, production workflows | Medium | Excellent |
| 96 kHz Highest-quality output for professional-grade audio. | High-end production, voiceovers, archives | Large | Exceptional |
Note: While 96 kHz clips can be downloaded in multiple formats, MP3 and OGG compression will reduce audio quality. For best results, download 96 kHz audio as .WAV files.
Create Audio with Different Sample Rates
- Create a new project and select WellSaid Studio.
- Open Project Settings.
- Choose your preferred Sample Rate.
- Enter your script.
- To use the 48 kHz or 96 kHz sample rates, select a voice with the Caruso option in the style/model dropdown menu.
Note: Sections that have already been rendered will remain in their original sample rate. To change them, you’ll need to re-generate those sections using your preferred sample rate.
FAQs
Q: Are multiple sample rates available in Legacy Studio - Standard projects?
A: No. Multiple sample rates are available only for Voices using the Caruso model.
Q: Can I render different takes in the same project at different sample rates?
A: Yes. Sample rate is set at the project level, but you can still render audio at your preferred rate when using a Caruso voice. Standard and Partner models will always render at 24 kHz.
Q: Does the sample rate affect downloading Closed Captioning files?
A: No. File types are independent of sample rate, so downloading captions and transcripts (SRT, VTT, TXT) and audio files (WAV, OGG, MP3) is not affected.
Q: I want access to higher sample rates without upgrading. Is that possible?
A: Higher sample rates are currently available only on Enterprise plans. Contact your Customer Success team to learn more about upgrading your subscription.
