Here is a list showing what you can approximately do with 1 GB (music, video, email ...) knowing that the actual final result will depend on the compression formats used: Simple email: 20 kb, or 50,000 emails with 1 GBEmail with attachment: 500 kb, or 2,000 emails in 1 GBWeb page without images: 100 kb, or 1,000 simple web pages with 1 GBWeb page with images: 500 kb, or 200 web pages with images in 1 GBMusic (128kbit/s) 1 MB/minute, or 1,000 minutes of music with 1 GB, which is about 17 hours of musicLow definition videos: 5 MB/minute, or 200 minutes of video (3h20) with 1 GB.HD videos: 20 MB/minute, which amounts to 50 minutes of Full HD video

Knowing that a 1h30 movie is about 680 MB and that there are 1000 MB in 1 GB, I'll let you do the math ^^ (it should be about 2h15).

Hello,

A commercial audio CD has a capacity of 700 MB and offers a maximum listening time of 75 minutes, in AIFF format, which is uncompressed.

Then it depends on the compression method:

- lossless compression like Apple loudness: which rewrites the file differently (using series of zeros or ones as factors, "6x0" taking up less space in bytes than "000000"). The software that plays this file decompresses it with the same algorithm and therefore reproduces the original sound without altering it.

- lossy compression, the most notorious being mp3, which divides the memory usage rate by a factor of 10 or 11 while brutally stripping away anything it can find of smooth and bucolic harmonics.

I experienced this: I had fun compressing a string quartet into mp3 (Beethoven's 14th, but it doesn't matter), and I suddenly wondered why the cellist took advantage of my turned back to mess around on my computer and suddenly switch to the bagpipes :-(

Otherwise, if it's to listen in a Deux Chevaux stuck at a red light next to a jackhammer, mp3 offers a good compression rate of the sound signal and should allow you to fit something like several hours of preparation music for your ENT consultation, as it is known (it's a medical fact) that the poorer the sound, the more likely we are to turn up the volume :-(
