Best Optimization Method

Set an appropriate audio bitrate

• Generally, use a standard audio bitrate of 128 kbit/s.
• If the audio file is still too large, you can reduce it to 64 kbit/s or 96 kbit/s, but it is not recommended to go below 64 kbit/s.
• If the sound quality is noticeably degraded, you may increase the bitrate appropriately, such as 192 kbit/s.

Choose an appropriate audio sampling rate

• Generally, use the standard sampling rate of 44.1 kHz.
• If the audio file is still too large, you may reduce it to 22.05 kHz, but it is not recommended to go below 22.05 kHz.

Set an appropriate number of channels

• Normally, choose stereo (dual-channel).
• If the audio file is still too large, you can set it to mono (single-channel).
