Can someone here help me?
If I play a 48kHZ wav in a different sample rate host , for sample , I set my host working sample rate to 44.1khz ,so 48kHZ wav will become pitch down and slow down,but how much?
is there any formula or tool to calculate this ?
For example. my song tempo is 160, C major, and in 48K, when I play it in 44.1K ,what tone will it go ? and what tempo will it be changed?
sample rate and tempo and pitch

just use rbrain from voxengo to resample the audio file if thats what you want to do.

the tempo is easy because it's directly proportional to the sample rate;
(160*44.1)/48 = 147bpm
pitch requires a more complicated formula:
1200(log(ratio))/log(2) = cents
1200(log(44.1/48))/log(2) = -146.7
so your song will go 146.7 cents flat, about a semitone-and-a-half.
