When I bought my iPhone, I bought the 32 GB version of the 3GS. At the time I knew that that would be a small amount for what I wanted to do, but as my music library increased I could see it chewing up more and more of that 32 GB memory. In fact it was over 9 GB. I wanted and needed more room for video and other media. I also knew that I had to trim the size of my music before I got an iPad. Luckily for us Apple added something to iTunes that will help with that, after the break.
Most people are not my sister. My sister is a College Trained Musician. While I play instruments, I am nowhere near to my sister for being able to hear differences in codecs and bit depth for music files. I have listened to two pieces of music, one at the 256 kHz sample rate versus the same file downgraded to 128 kHz sample rate.
I think most of this inability is due to waxy buildup in my ears, my years as a Reactor Control Tech for the US Navy, and old age. So, When I saw the checkbox in the Options section of the summary page of the syncing screen for my iPhone in iTunes it came as a shock.
I click on the option and told it to apply. About two hours later I have about half of the original files size reduced. I got about 4 GB back on my iPhone! I can’t tell the difference, and it did not change the original files. The changed files are on the iPhone, while the original files are still their 256 kHz sample rate.
So if you are not an audiophile with high end equipment, then you can recover some much needed space on your iPhone/touch/iPad device.
I’ve since created a video on this topic. You can find it here.
