Speeding Up FLAC - What Helps Most?

For converting multiple .wav files to FLAC (48k, 24bits) what is a good starting place on a tight budget: the software (OS and/or DAW), the chipset, the amount of RAM, the graphics card, the storage, or the CPU? And if it's the CPU is it how many cores or speed per core?

Comments and suggestions for speeding up FLAC conversions are welcome.

best,

CPU.

Multiple cores only help if you either do multiple files at the same time or if your specific encoder the multithreaded. In doubt I'd go with faster fewer cores. Which encoder are you using?

Thanks,

Audacity seems to work pretty well for me except for the fact that I don't really need to hear the files. However, to save space I do like to trim heads and tails, and Audacity displays about as fast as anything else I've tried (proxy editing seems confined only to the video realm--but why it's not done for audio? well that's a different topic).

The converter from FLAC (with front end) was OK but (IIRC) Audacity left me with more peace of mind that everything had been converted properly.

best,

john

I'm pretty sure you should go for pure per-core speed then. Audacity should use the open source flac encoder which IIRC is single threaded. You are unlikely to exceed the need for 4 cores that you'd get with a fast i5 or so.

Oh and no AMD, sorry. In this particular area of performance they are far, far behind. It's a shame, really.

You should get a converter that can handle multicore (what it usually does is it encodes multiple files at once).
Foobar or Xrecode, for example. Foobar will ask you for flac.exe, which you can get in one of the zipped bundles here.
CUETools is another one, with various FLAC encoders you can use.

I use the audio converter that comes with AIMP 3 audio player. It has multicore support so it can convert as many audio files as you have cores at the same time.

Hi, jabney! Why coding speed is so important to You? If i understand correctly, it isn't tracking to FLAC instead WAV on the fly. If Yes, then independently from frontend, the encoder will be flac 1.2.1b or 1.3.0 FLAC - changelog

It doesn't matter which DAW do You use, but BTW Reaper (DAW) and foobar2000 (player) have very handy built in batch covertors. You can set up Your queue and let the computer does the job when You sleep at night
