iTunes File Formats: AAC Protected .mp4

I have just opened my new HiFiMan 601 DAP in search of higher, portable fidelity.

The player seems to recognize WAV files - my main motivation for abandoning the iPod, as I would like to load up the player with WAV files for critical listening or favorite music for the gym.

However, it does not seem to recognize mp4 files.

I was hoping, for more casual listening and Audiobooks, to also transfer my iTunes library, which although I am still searching several external hard drives, generally seem to be in the format as described above.

Can I convert this file format to WAV or another format which could more easily be read by this player?

Or is this the proprietary format which requires an iPod and iTunes?

Thank you,

I don't know about the items Shatern listed above but I'd bet they will do the trick for you.

I've seen as welll online, some apps which say they will play and/or convert protected files to some other format.

What is generally going on is that they are playing the file, and ripping it off a cache. So it seems immediate. Almost. Most of these turn the files into mp3. Some will do WAV or WAVE.

There's little sense in coverting compressed files into WAV/WAVE though. They'll just eat up a lot more space and sound no better.


As the file itself plays. So it's time consuming.... but free. Allowing for the time consumption, if you like myself have a thousand or three, protected files you want to convert, everything will depend then on your tolerance levels and your budget.

There's several out there which offfer a trial period too.

Or..... you can start burning them all to CDR and going that way you instantly make backups for your music... and you're out the cost of CDRs and your time.

I'd bet too your player will take some other compressed file type, like Windows... WMA. Or mp3 as well.

Google for audio file format converters you'll find plenty. Or streaming audio recorders, they'll do it too.

Sound pad is what I got... I think.

the last option... if you're willing to pay for it and itunes is still doing it is to buy the upsampled, 128 protected m4p file to their newer high res 256 non protected m4a file type.

It's still AAC though. Just no DRM security is applied then. This option used to be in itunes on the right hand side of the Music store window... about upgrading. it came out to around $0.30 ea. IF they still had rights to sell the music itself. They don't always keep everything forever.

The scan would reveal what they could upgrade for you in a separate view. So you could actually pick which ones you wanted to pay to have the DRM released, and the content repalced by a 256 bit file vs. your 128s now on hand.

Good luck.
Are the protected files all m4p files, or just m4p files that were downloaded from iTunes? If they're iTunes bought files, you can burn them to CD and rip the CD. The convenience of that depends on how many files we're talking about.

That sounds like a relatively straightforward solution - thank you.

Generally, they are files (and also audiobooks) that I downloaded from iTunes.

I don't have a huge library, and in the absence of a WAV option, I think I generally used so called "Apple Lossless".

I do want to figure out this puzzle before loading up the new HiFiMan player for a test drive at the gym.

Experimenting tonight using EAC, I notice that WAV files ripped from CDs using EAC are in fact "tagged" easily enough, at least with the track title information.

However, it seems if I copy WAV files as a test to the HiFiMan player, they seem to play back only in alphabetical order.

Therefore, I would have to manually create "playlists", by adding sequential numbers to the beginning of the filenames?

If so, that could almost make me go back to an iPod.

But of course if convenience were my goal, I wouldn't actually be a self respecting "audiophile".
In order to convert iTunes audiobook, you need an DRM audiobook converter to help you strip the DRM protection as well as transform your drm files to common audio files. You can take a look at this link to help you get rid of any limitations.
As for iTunes movies, they are encoded in AAC protected MP4 format or called M4V format. 
As for iTunes music, they are encoded in AAC protected MP3 format or called MP4 format. 
Here, I will share some small tricks of iTunes AAC protected audio files. If you would like to convert iTunes audio files to other unprotected format, like MP3, you can have a try of iTunes DRM Audio Converter for Windows. Hope this software is helpful for you. 
In my opinion, to remove DRM protection from iTunes movies on Windows, you need to crack DRM encrypted in all iTunes movies at first. We all know that iTunes movies can be played on Apple devices only. DRM Media Converter for Windows is the program for me to crack DRM  protection from iTunes purchased and rental movies. After conversion, all these videos are lossless quality. You can enjoy non DRM protected iTunes videos and TV shows on Samsung TV, android phone, Windows PC and other devices freely. Maybe you can check more info on Tuneskit Software. Hope this tip is useful to you.
