How to Make Audio Settings Before FLV Encoding in Server Side
Specify an incorrectly bit rate may cause encoding failure. Here give a table to describe the dependency relationship between the audio bit rate and the audio sample rate. Hope it helpful.
Audio Settings
The following table describes the dependency relationship between the audio bit rate and the audio sample rate. The available bit rate values are related to the specified sample rate. Specify an incorrectly bit rate may cause encoding failure.

| Bit rate | 8 Kbps | 8 Kbps | 32 Kbps |
| 16 Kbps | 16 Kbps | 40 Kbps | |
| 24 Kbps | 24 Kbps | 48 Kbps | |
| 32 Kbps | 32 Kbps | 56 Kbps | |
| 40 Kbps | 40 Kbps | 64 Kbps | |
| 48 Kbps | 48 Kbps | 80 Kbps | |
| 56 Kbps | 56 Kbps | 96 Kbps | |
| 64 Kbps | 64 Kbps | 112 Kbps | |
| 80 Kbps | 80 Kbps | 128 Kbps | |
| 96 Kbps | 96 Kbps | 160 Kbps | |
| 112 Kbps | 112 Kbps | 192 Kbps | |
| 128 Kbps | 128 Kbps | 224 Kbps | |
| 144 Kbps | 144 Kbps | 256 Kbps | |
| 160 Kbps | 160 Kbps | 320 Kbps |
