Saaay. I Have a Tech Question

Say you have a .wav file.

Say it is not capturing the sounds of a conversation between two bats reviewing a performance of the Moscow Philharmonic doing a fusion mash-up performance of Chinese opera and baroque classical.
Say instead its just something of lower bandwidth and complexity, like industrial  or dance.
Say its run time is an hour and a half long. 
Would there be any non-worrisome reason that, say,1.58 gigabytes would be a reasonable size for that file?

1 Well, a 60-minute audio CD would produce an uncompressed WAV file around 600 megabytes in size, so that sounds a bit large.

2 According to my calculations, 1 hour 30 minues of 16-bit dual channel samples (4 bytes) at 48 kHz take 1036800000 bytes, or basically a gigabyte. It's still a bit short of 1.58 G.

3 Oh.

Well its 32-bit .wav so that's not nearly as far off as I'd feared.

4 That is within range for a .wav file, given the details you have provided.

5 .wav, the uncompressed .bmp of audio....

6 Expanding .wav to 32 bits is a nice touch.  Everyone has infinite storage and works as a professional audio engineer, right?

7 I have Japanese DVDs that are recorded with PCM audio. But 32 bits, that's taking it too far.
