问题描述
我正在与mp3文件的采样率将其转换成CAF格式实验。
afconvert -f卡福-d LEI16 @ 44100 ./fricatives_play_all.mp3 ./test.caf
afconvert -f卡福-d LEI16 @ 22100 ./fricatives_play_all.mp3 ./test.caf
afconvert -f卡福-d LEI16 @ 12000 ./fricatives_play_all.mp3 ./test.caf
afconvert -f卡福-d LEI16 @ 20100 ./fricatives_play_all.mp3 ./test.caf
afconvert -f卡福-d LEI16 @ 15100 ./fricatives_play_all.mp3 ./test.caf
afconvert -f卡福-d LEI16 @ 14100 ./fricatives_play_all.mp3 ./test.caf
afconvert -f卡福-d LEI16 @ 13100 ./fricatives_play_all.mp3 ./test.caf
afconvert -f卡福-d LEI16 @ 44100 -c 1 ./fricatives_play_all.mp3 ./test.caf
afconvert -f卡福-d LEI16 @ 13100 -c 1 ./fricatives_play_all.mp3 ./test.caf
afconvert -f卡福-d LEI16 @ 22100 -c 1 ./test ./test2.caf
I am experimenting with the sampling rate of the mp3 file to convert it into caf format. afconvert -f caff -d LEI16@44100 ./fricatives_play_all.mp3 ./test.caf afconvert -f caff -d LEI16@22100 ./fricatives_play_all.mp3 ./test.caf afconvert -f caff -d LEI16@12000 ./fricatives_play_all.mp3 ./test.caf afconvert -f caff -d LEI16@20100 ./fricatives_play_all.mp3 ./test.caf afconvert -f caff -d LEI16@15100 ./fricatives_play_all.mp3 ./test.caf afconvert -f caff -d LEI16@14100 ./fricatives_play_all.mp3 ./test.caf afconvert -f caff -d LEI16@13100 ./fricatives_play_all.mp3 ./test.caf afconvert -f caff -d LEI16@44100 -c 1 ./fricatives_play_all.mp3 ./test.caf afconvert -f caff -d LEI16@13100 -c 1 ./fricatives_play_all.mp3 ./test.caf afconvert -f caff -d LEI16@22100 -c 1 ./test ./test2.caf
我用不同的采样率如上述转换的MP3文件
到CAF文件。例如，对于一个38.5 MB的文件：
I have used different sampling rates as above for converting mp3 filesto caf files. For instance, for a 38.5 MB file :
采样率大小
15100 72.6 MB
14100 67.8 MB
13100 63 MB
Sampling Rate Size15,100 72.6 MB14,100 67.8 MB13,100 63 MB
正如你所看到的文件大小减少了与较低的采样率，但
质量逐渐减小。如果你能提供更深入
这个问题，我真的AP preciate它。
As you can see the file size reduces with the lower sampling rate butthe quality gradually decreases. If you could provide more insightinto this problem, I would really appreciate it.
推荐答案
如果这是一个立体声文件，你可以将其转换为单声道。你还可以使用IMA-4：1的COM pression，从而降低文件大小为25％，但它确实有所降低的质量。
If it's a stereo file, you could convert it to mono. You can also use the IMA-4:1 compression, which reduces the file size to 25%, but it does reduce the quality somewhat.
