I have been using foobar and dbpoweramp as a flac to wav converter but sometime I have issues about sound quality and losses on record. I checked on web I found Switch Sound File Converter, Xilisoft Audio Converter, Stellar Audio Converter. I tried them but just for few songs and not sure. Do you have any suggestions any experiences. I also can pay for it, kind of a obsession for me :)
Before you spend any money here's 2 more free ones. Handbrake should be able to do anything you need. Most people think its for video, but it can do audio as well. Its considered one of the better applications if you're looking for good quality. Clementine music player is the other. Its transcoder is very simple to use, but it works surprisingly well.
I've used Trader's Little Helper for many years without any issues to easily convert flac files to wav format. It also supports many other conversions and it's free. When you install it be sure to avoid installation of any optional software which may be included if you don't decline it. http://tlh.easytree.org/
Nowadays most music files are DRM protection, I tried multiple online free video converter, none of them work. The only one works well for me is DRmare Audio Converter which is a commercial software, it works just well. If you don’t care about spending some money, just give it a try.
The experience for me to use Audio Converter Software is to use Apple Music Converter Mac to remove DRM protection and convert Apple music to MP3, AAC, etc at 30x faster speed with lossless quality. We know all purchased or rented Apple music are DRM protected, it can be played on Apple devices only. Now you can use this audio converter software to crack DRM protection and convert audio to multiple compatible formats. It will be much convenient for all users to enjoy Apple audio freely.
I personally choose AudFree DRM audio converter to use on my laptop. This tool supports converting all types of audio files. Besides converting FLAC to WAV with lossless quality, it can also convert Apple Music, iTunes songs, Audible aa/aax, and common audio files to other formats at 30X faster speed.
