Dear CommunityI had loaded a lot of obscure lectures and poetry readings into my music library using WAV. Little of it can be tagged using remote databases and now I wish to improve the tags but find myself blocked in every direction.If I try and change it directly by opening up the music file and going to Properties, once I have changed the permissions and go to details, I cannot edit. I have seen some indicate that it needs to be set on 'values' for me to have permissionto edit title.

No luck there either. When I click on a field like 'Title' the panel remains blue regardless of whether I right click or not, or left click for that matter. When I strike a letter like 'B' I am taken to the Bit Rate field.I do not find any metadata tagger 3rd party software that seems to cure. Some people advise loading into Audacity or Adobe Bridge but that seems like an enormous end around. All the 3rd party taggers seem to avoid WAV because I understand thereare two many variables.Now, if this is correct and I have no option to properly tag a WAV file that makes the format a must to avoid and means Microsoft has ceded the field entirely to MP 3. If that is the case and I need to convert hours and hours of files fromWAV to MP3, what guarantee do I have that the data, such as it is, will carry over. I cannot go back and rip this audio again, it is too rare.
Hi JoelYes this has always been a headache for wav. I believe it is simply due to the size of wav. Back when they were developed (partly by MS) they were for very small sound files (start-up - alerts etc.) and not expected to be used for largeaudio files so a tagging system was never developed. However, information can be added to the various fields in WMP but this does not stick to the file of course.Converting the files to mp3 would mean adding the data there subsequently in most cases so it may be best to stick with what you have already.As others have suggested there are limited tagging options for wav. By using the 'Audacity' audio editing suite. That would mean quite a lot of work for you, but I'll explain further if it is of any interest.
In the meantime here is the link to the Audacityinfo pages (the program can also be downloaded there) and below that a 'properties-details' box of a wav. File saved with audacity - somewhat limited but maybe of some use!Cheers, Ric.No longer active in this community from July 2018 - Regards to all - RW.
I've heard that using lossless audio compression gives hugely improved sound quality over MP3. Should I consider using it?TaylorA process is used when music is compressed into MP3 to discard all the sounds a machine thinks the human ear can't audibly perceive, thus vastly reducing the amount of storage needed to hold entire albums.The problem with this form of 'lossy' compression is that many people can perceive the bits of audio discarded and are left with the feeling that they're listening to lower quality music. This is where the term 'bit rate' comes into play - the lower the bit rate, the more data that's been thrown away and, therefore, the lower the audio quality.What lossless audio compression does is retain every single bit of detail from the original recording, while still managing to reduce file sizes considerably. A typical song as it is on a CD takes about 50MB of memory.
A decent-quality, 256kbps MP3 of the same song is around 5MB - that's a massive amount of data lost in the compression process. A higher bit rate MP3 will give you a better quality audio file, and a larger file size, but it can still never touch the quality of the original recording.

This is where lossless audio comes into play.A typical song compressed into a lossless format, such as FLAC or Apple's Lossless audio format, clocks in at about 30MB on average. Although this is much smaller than the original 50MB file on a CD, it still retains every last bit of information.How is this possible?An extremely complex mathematical algorithm recognises sound patterns in an audio track. For example, let's say you have a series of numbers: 1234 1234 1234 1234 1234. Instead of using up storage space to remember each of those 20 digits, the lossless algorithm simply remembers '1234' and that it repeats five times: 1234 x 5. Notice how only five digits are used in total, instead of 20. Using this process, significantly less storage is needed overall.To use lossless audio, you'll need a player that supports it. Some players, such as the or, support the FLAC format.
On the other hand, and ranges support Apple's own lossless format, ALAC. The main reason to use lossless audio is if you use a high-quality hi-fi speaker system at home, or if you use very expensive. If you're just listening to music on your iPod, using the bundled headphones for the 30 minutes you commute to work, you don't need lossless audio.If you're still unsure whether lossless audio is for you, the best method is to listen to a song in MP3 and the same song in lossless format. If you can't honestly tell the difference, stick with MP3. It's the most widely used format and you'll get heaps more music on your portable player by using it.If you can tell the difference and appreciate the original recording quality of CDs, you should definitely consider a lossless audio format. Remember, you could always use lossless at home and MP3 on the move, since computer hard disks are vastly more capacious than portable music players.Good luck!
