LOL. Music fileS man. Not even videos would regularly be that big.

That's not too big a big file size at all depending on how many songs you wish to have resident on the device, in lossless format for best sound quality, which is the whole point of using an app like CanOpener.
 
I understand the efficiency of MP3 and AAC, but they have seen their better days, and were originally intended to offset the very high cost of storage media around 10-15 years ago.
 
Storage is now getting cheap enough that lossless makes the most sense if sound quality is important.

To devkerr,
 
I have really been enjoying CanOpener, not just for the crossfeed function but also for the little touches like the very precise volume control and the dosimeter. I would like to add one suggestion. On my computer I use a crossfeed app/room simulator called TB Isone and it does a great job of applying crossfeed, with the added advantage of a crossfeed compensation circuit that automatically balances the frequency response when crossfeed is applied. The bass boost when applying crossfeed in CanOpener is very noticeable, and I have been trying to EQ it out using the Equalizer and the Pencil EQ. Is it possible to add a crossfeed compensation circuit to CanOpener? If not, do you have any advice to balance the sound using the EQ?
 
Thanks.

320kbps is lossless too O_o and storage isn't cheap, most people's iphones can only hold 32gb.

12gb music file would be close to 100,000kbps. That's close to 100x flac rate. Either that or it's like 100 songs tied together. Regardless the fact it can't play a 12gb file is more of a joke than a serious problem.

As you consider other headphones to add to the CanOpener library, you might be interested in the analysis here, where 2,000 headphone comparisons by head-fi'ers, as posted in the thread "Rank The Headphones That You Own," are analyzed.

That's not too big a big file size at all depending on how many songs you wish to have resident on the device, in lossless format for best sound quality, which is the whole point of using an app like CanOpener.
 
I understand the deficiency of MP3 and AAC, but they have seen their better days, and were originally intended to offset the very high cost of storage media around 10-15 years ago.
 
Storage is now getting cheap enough that lossless makes the most sense if sound quality is important.

 
True2. But yeah, the app can't handle too many songs. Hopefully the next update will fix it. For now, I'll have to use another player. I miss how easy it is to use the Pencil EQ and not using this player's parametric eq.

 

[Hapster]

  I'm sure he meant a total of 12gb and not a single 12gb track.

Well if he was talking about 12gb I'm not sure what device he's using, because I have 18gb of music on my iphone and have no trouble with the app.

Stated there iPod Touch 5G. 64gb version though
And I don't know why, probably it's wrong on my side. are those 18gb in the FLAC folder?

 

[mikemike99]

Just tried the polarity button, depending on the recording it can sound very good.
 
But I couldn't find an explanation how it works exactly, more like "could enhance the sound of a mono recording".
 
Can Opener shows -L and -R instead of L and R.
 
Is it like connecting the speaker cable the wrong way? 
 
Regards Michael

 

[rtimmel]

Grr.  Is anyone else having this problem with CanOpener?  Lots of my files are compressed aac files with an .m4a extension. CanOpener will not play these files, seeing them as video files ("Video Selected!  Unfortunately Can Opener can't play video content.)
 
My guess this is a peculiar bug with my installation.  Otherwise, I would expect to see other comments about this given that .m4a is a fairly common aac encoding extension and I think it is Apple's default for audio. I've tried reinstalling the app to no avail.

I have over 30 GB AAC--Files on my phone, all with m4a-extension and everything works fine in can opener.
 
How do You generate Your files?
 
Maybe something wrong in the file header?

 

[rtimmel]

That is so weird.  The files were all encoded through iTunes, so nothing fishy there.  The are at 320 kbps and I don't remember if they are done at a vbr or not, but I think they are not. The worst part is that I've gotten rid of most of my CD's over time, and just have the encoded files backed up.

AAC is worse than 320KPS MP3 tbh.

I hope you're kidding. ALAC is lossless it CAN'T sound worse
