Flash Media Encoder referred to as FMLE

The following table lists the relationship between the sample rate and the samples of each frame of audio and the duration of each frame, in milliseconds.

MP3 44K 22K 11K
Stereo 1152 1152/2 1152/2
Single channel 1152 1152/2 1152/2
Duration per frame 26 26 52

Duration per frame = N_samples * 1000/samples

For example, 44100 Mono, each channel sample number is 1152 (MP3 per frame sample), then Duration = 1152 * 1000/44100 = 26.1224489795918 ms

For 11K dual-channel scenarios, duration = 1152/2 * 1000/11025 = 52.2448979591837 ms

For 22K mono case, duration = 1152/2 * 1000/22050 = 26.1224489795918 ms
