fre:ac is a free audio converter and CD ripper with support for various popular formats and encoders. It converts freely between MP3, M4A/AAC, FLAC, WMA, Opus, Ogg Vorbis, Speex, Monkey's Audio (APE), WavPack, WAV and other formats.
What I'm trying to do is now convert that .wav to a .flac. I've seen a few ways to do this which all involve installing a converter and placing it in my environmental PATH and calling it via os.system.
I have 50gb of flac files, and I want to convert them into mp3s. Previously I have used fre:ac, but it crashes very often and a few months ago It just stopped working and for some reason started making corrupt files (the flac files were fine btw). I'm having difficulty looking for an alternative because the internet is filled with these online converters and unclear free trials.
If you take an album in FLAC (or APE) and convert it to WAV using 5 different converters you will find that all 5 newly created WAV-versions of your album sound different. What the heck is going on here? Why do they sound different!? There are many dozens of converters out there that can do the job. I don't have the time to go through them all to find the best for the job. So, the point of this thread is to cross-fertilize, collect member feedback and come up with a list of top-three converters out there.So my question goes to all those addicted to best: what is your favorite FLAC-to-WAV converter?
I am using a mini computer with i7 8650 series processor, with passive cooling. The signal from the computer via USB AudioQuest Diamond is fed to the USB-SPDIF Singxer SU-1 converter. Then from it SPDIF is fed to the DAC. A Samsung 970 Pro SSD M2 is installed inside the computer, with the software installed. The music files are stored on a 2.5 "HDD connected to a SATA cable from 3M. This is the best I could find! On such a source, the difference between FLAC and WAV files is very clear. I find the package source configuration to be the best in terms of getting good sound.
Well, I guess I'll leave this post up in case anyone else is having the same problem, but it turns out I'm just dumb and didn't try changing the one setting that was causing the issue :D
For whatever reason, filtering it through the sample rate converter, even if it was set to the same sample rate as the original file, massively increased the bitrate. I took out the filter and all of a sudden I have 900kbps, 48khz ALAC files. Fascinating.
I believe using sndfile-convert (libsndfile) does not have this problem. Likewise, I believe it can be avoided by using mplayer to decode the m4a before encoding it with ffmpeg or flac. I think soundKonverter on KDE may do this for you.
And this is the ouput from ffprobe on a flac file:
Stream #0:0: Audio: flac, 48000 Hz, stereo, s32 (24 bit)
And don't forget to check the tags/metadata on the file. I was surprised to see my mail address in the tag/metadata. And ffprobe show more mtag/metada as Easytag.
Now I had access to the Lidarr container I needed to check to see of the two dependices 'ffmpeg' and 'awk' needed to run the 'flac2mp3.sh' script were already installed. This I did by just trying to run them and to my surprise both were already in the 'binhex-lidarr' container.
Login to your unread server and go to your Lidarr Docker WebUI and go to 'Settings > Connect'.
Create a 'Custom Script' trigger by selecting the + and then 'Custom Script'.
Name it something like 'FLAC to MP3' and select 'On Release Import' and 'On Upgrade' as the only notification triggers (these have been tested).
In the path find the script you just setup either the default script '/usr/local/bin/flac2mp3.sh' or your wrapper script.
I recommend FFMPEG to do that.
It works fine with tags and cover art (at least with my FLAC and embedded cover art).

If you deal with a lot of audio files, and work on multiple projects from time to time, it is imperative for you to have access to an efficient FLAC converter that can not only transcode FLAC to AC3 , WMA, MP3, etc., it must also be capable of doing vice versa such as AC3 to FLAC, MP3 to WMA, and much more. With that said, the following sections discuss about some of the best paid and free FLAC converter applications that can be installed on your computer, or can be accessed from a web browser.
The first program in the list that has been in the market since more than a decade now, and is appreciated by millions of users throughout the world is UniConverter by Wondershare. M4A to FLAC converter, that was earlier known as Wondershare Video Converter Ultimate, in addition to being an FLAC audio converter, also has several built-in tools such as video compressor, video editor, screen recorder, etc. to make your production and post-production tasks simpler. Furthermore, the software can recognize 1000+ formats for conversions, and can be installed on a Windows and Mac computer.
Set an output folder in the File Location field that is present at the bottom of the right window, and click the Convert to use Wondershare UniConverter as an FLAC audio converter. Note: In case you have imported multiple files and want to perform batch conversion, you can click the Start All from the bottom-right corner of the interface to begin the process.
Use the Output field present at the bottom to set an output folder where all the converted files should go, and click the Convert from the right area of the imported file to use the program as a free FLAC converter software.
With a neat and clean interface, CloudConvert is capable of recognizing 200+ formats for conversions. As for the FLAC converter, the web app can easily convert FLAC to AC3, AC3 to FLAC, WMA to FLAC, and much more. All in all, the portal is a good platform and can be considered the best FLAC converter for all types of transcoding purposes.
Audio Converter is an FLAC audio converter that lets you set the output quality of the converted file with the help of a slider that is present right on the landing page. The portal even lets you choose your preferred output format from the available tabs. In addition, you can also use this Internet app to create ringtones for your iPhone.
With add-ins available for both Google Chrome and Mozilla Firefox, Online-Convert can be integrated to your favorite web browser, and can then be exploited not only to convert WMA to FLAC, but also vice versa with ease. Also, the web tool also has other converters such as for documents, PDF files, images, and more.
With a single button on the landing page, this one can be considered one of the easiest FLAC converter solutions that can be accessed on any web browser regardless of the platform of the operating system you are using. The entire conversion process can be completed in three simple steps where you can upload the file, choose an output format, and begin transcoding.
Although a dedicated PC program is always good to be used as an FLAC converter because it offers unlimited number of conversions, fast uploading, quick processing, and much more, an efficient one might come with a price tag. If you are a professional, and work on several projects for commercial gains, a tool like Wondershare UniConverter would be your best bet. However, if the transcoding that you do is for personal use, and is not quite frequent in nature, using any online solution such as Wondershare Online Uniconverter would serve the purpose pretty well.
Then you can use another application such as dbPoweramp to create Flac files from your Wav files, this should preserve the information added by SongKong so that your flac songs have some basic metadata from Naim.
