Tagging of MP3/WAV?

[DoubleDecker]

Hi guys,

What do we use to encode information on our mp3 or wav?

I never have a problem with this since I burn my music into CD and send it off to whoever needs it. But recently someone has opt to receive mine in mp3 and wav format for their video. So how do I encode the information into both files?

Thanks in advance.

When you burn music onto a CD, the music originally came in a WAV format right? If not, how did you burn your CD?

Generally, WAV is the format to represent audio signals digitally in the computer. Because WAV files are usually very big and hence not portable, the MP3 format was created to intelligently remove non-critical parts of the information, resulting in a hugely reduced sized audio file.

The tradeoff is... the MP3 file is no longer 100% accurate. Parts of the audio signal has been thrown away, so quality may suffer. It also depends on what quality settings you encode MP3s at. Some can hear the difference, some cannot.

To generate MP3 files from WAV files, just use any MP3 encoder available on the internet for free. LAME is a good choice.

Actually I think I posted the wrong topic ... I'm confused over these ID3tag or Tagging terms. I apologize for the confusion...

What I meant was ... the information to be attached to the .mp3 or .wav files. Like Artiste, Year, Genre etc. Is that what is known as tagging?

Yes, I do have both .mp3 and .wav format for same tracks ... .mp3 is for listening and selection while .wav file is the one they will be using in the video. Now I need to input these information into my .mp3 and .wav, before I send it out.

And also...
1. Can my tagging be changed by someone else?
2. Can it be locked down to my .mp3 and .wav so nobody can alter these information?
3. In the event that it can be locked down, will I still be able to do further mixing and mastering to my track?
4. So tagging should be done prior to mixing or it can be done after the mixdown?

Sorry for these long list of queries.

u cannot tag ur Wave files. ( i hope im right ) .. lolx..

there are various "taggers" for audio/video files. the term tagging is broad in meaning so im only going to talk abt metadata in mp3 files; WAV has no tags/capability to store such metadata for viewing. The common tagging for mp3 is ID3. There is ID3v1 and ID3v2. The former is used for older files/players and for compatibility with legacy media. In any case ur reading/writing media is older than the creation of ID3v2, it can only read/write ID3v1. WMP has its own tagging for its wma files, but u can edit ID3 (mp3 files) tags through it.

U can simply edit an mp3 ID3 tag through an audio player. There are taggers available free from www.majorgeeks.com :lol: Anyway wouldn't using wav for the video increase the video size tenfolds?

gutturalpiss, you are all correct until you mentioned "wouldn't using wav for the video increase the video size tenfolds?" ha..ha..

for video, when using the DV compression, 1 hour of footage is about 13Gb. With audio.

For audio, when using WAV compression, 1 hour of stereo is about 600mb.

when working in video editing, the audio file size is the least of worries. :wink:

My job is just to compose the music and send it up to them in both .mp3 and .wav, as for the rest of it, I ain't knowing much because I don't deal with video post-production. Moreover, the point of contact is the video producer and the client, I don't deal with the client, only the video producer.

It dependent on the client too. With the kind of budget they (my client over here) have, I think all these are like "nothing" to them. Get it done no matter what's the cost.

wow, you client so good!

 

[DoubleDecker]

Not my client... and not local client definitely... (locals would price money above quality) :lol: :lol: :lol: ... the video producer's client. I'm only working behind the scene for music that's all.

yep i dont know abt that. since wav itself is big. and i often see DVDs encoded with mpeg layer 3 audio. So thought that was the norm :lol:
