Audio Export Formats¶
Speech Studio supports multiple audio export formats to suit different use cases. This guide covers the available formats, their characteristics, and when to use each one.
Supported Formats¶
| Format | Extension | Compression | Best For |
|---|---|---|---|
| MP3 | .mp3 |
Lossy | General use, sharing, web content |
| WAV | .wav |
Uncompressed | Professional editing, highest quality |
| OGG | .ogg |
Lossy | Web embedding, open-source projects |
Format Details¶
MP3¶
MP3 is the most widely supported audio format. It produces small file sizes with good audio quality, making it ideal for:
- Sharing via email or messaging
- Uploading to websites and social media
- Podcasts and online content
- Mobile playback
Speech Studio exports MP3 files at high bitrates (up to 320 kbps) to preserve the quality of the neural voice output.
WAV¶
WAV files are uncompressed, providing the highest possible audio quality with no data loss. Use WAV when:
- You plan to edit the audio in a professional DAW (Digital Audio Workstation)
- Quality is more important than file size
- You need a lossless master copy for archival purposes
- The audio will go through further processing or compression later
File Size
WAV files are significantly larger than MP3 or OGG files. A 5-minute audio clip may be 50+ MB in WAV format compared to 5 MB in MP3.
OGG¶
OGG Vorbis is an open-source compressed format that offers quality comparable to MP3 at similar bitrates. It is a good choice when:
- You are embedding audio in web applications (OGG has good browser support)
- You prefer open-source formats
- You need a balance between quality and file size
Changing the Export Format¶
- After generating your audio, click Save or Export
- In the save dialog, use the Format dropdown to select your preferred format
- Adjust quality settings if available (bitrate for MP3, sample rate for WAV)
- Choose your save location and click Save
Default Format
Set your preferred default format in Settings > Default Audio Format to avoid selecting it each time. Most users find MP3 at 192 kbps or higher to be a good default for everyday use.
