Re: Bitrate conversion
WAV files are usually specified in terms of sample rate, bit format and number of channels rather than in terms of bit-rate.
For standard PCM WAV files, the bit-rate = sample rate x bit format x number of channels
Your 1536Kbps is likely to be 48000 Hz, 16-bit stereo (2 channels).
48000 x 16 x 2 = 1536000 bits per second = 1536 kbps
However it could be 48000 Hz 32-bit mono (unlikely) or 24000 Hz 32-bit stereo (more unlikely), or 12000 Hz 16-bit 7.1 (8 channels), or any combination of sample rate, bit-format and channels that = 1536000.
Assuming that the file is 16-bit stereo 48000 Hz (48 kHz) and you want it to be 16-bit stereo 44100 Hz (44.1 kHz), all you need to do is to import the file into Audacity, change the "project rate" (lower left corner of the main Audacity window) to 44100, then export as 16-bit WAV (default).
