I run Gentoo on a number of platforms, either x86 or Rpi. I've grip'd my CD collection into WAV files, and MP3 them when needed, but don't like the format (basically GenZ cassette quality, i.e. junk).

I'd like to play them in easily accessible categories for my own (superbly artistic) accompaniment, and am wondering which of the many pseudo-DJ apps might meet my very stringent requirements. ALSA preferred, playlists should conform to a recognized format, no need for abusing vinyl onstage (no vinyl, no stage), but such things as live cross-fade would be useful since I sit at an 86-key epiano with guitars ready to hand.

Any suggestions much appreciated.

mixxx

edit: and flac

Great suggestion, didn't know about it. Thanks.

You have to rip music in a high quality first. Not sure .wav isn't good. Pretty sure it and mp3 can be set to lossless.
flac is popular.

I've ripped all my CDs and a heap of old cassettes into WAV. Never tried FLAC - looks interesting.

Has anyone looked into this:

flac is lossless (like wav - mp3 is not).

Advantages over wav include selectable levels of (still lossless) compression and (a very useful one for me) TAGS!
Especially if using them in something like Mixxx, filenames alone limit the available info a lot.

Ah, yes. Most of my ? rip-offs are named Track-01, Track-02 etc ad nauseam. Thought of writing a script to clean things up, and got halfway there, but I'm a long-term devotee of the Three Perl Virtues: Laziness, Impatience, and Hubris.

There are a few tagging apps that could save you reinventing the wheel, which "fingerprint" the files and query online db's.

Been a while since I used them but I recall the "KDE one" (edit: kid3) to be pretty effective.

Thanks for that; didn't know there were any such things. Don't use KDE but I'll take a look for others.

go to the Mixxx development site compile it your self with all the stuff needed to play read up on what you need to actually use it fully. most builds of Mixxx for distro's are very limited you will need 1.11.0 or newer. it will easly find your music and create a data base that you can find everything with key word searching and create play list from just history of played songs.

reason I say compile it your self is because there are some thing like flacc that you have to compile disto's are unable to distribute it. but you are able to build it.
then compile it for your cpu Mixxx can be a work horse if you build it for your system. and gentoo is set up for that. good luck.
you can try the latest builds of 12.0 that are really pretty good. https://github.com/mixxxdj/mixxx

Useful advice. I'm planning on using it with the Rpi, so this is quite relevant.

I don't think that's the case - I use the debian package and it includes support for flac & mp3 and everything else I've thrown at it.

Unsure what distro you're using on your pi, but 1.10 is in the wheezy (stable) repo and 1.11 is in testing.

You may have a bit more fun getting the requirements and dependencies in order for the build process - that's all taken care of for you if you use the package.

It might indeed be worth it for processor optimising, but I've got no experience with that so can't advise.

I started a git repo today of the slackware build I been using to build the latest development of MIXXX
right now development is 1.12.rev

it is for Slackware 14.1 Well this is what I been using for a long time thought I share it with you.

you can edit the mixxx.Slackbuild in the /buildmixxx/mixxx for your cpu by editing the type and the amount of cores.

get it here. Slackware-mixxx-devel-build-script or git clone https://github.com/Drakeo/Slackware-...ild-script.git

I use this version now it has a lot more options then 1.11.0
you will need jdk or openjdk to compile it.
