In other words, take the result of the Quantization phase and convert it to 1s and 0s to compress it. Now, the 'encoder' part of the codec has (very broadly speaking) two tasks: first, 'Quantize' all the input signals. Next, a codec's job is to code(encode) a raw file with data in order to compress it but retain quality and then to play it back the codec must decode the result. It is specifically designed for audio files. It is named MP3 because it's part 3 of the MPEG1 suite of codecs. I'd appreciate any help! Thanks!įor those who want to know more, I'll add a few lines about what.

)ĭo you need a license to make new software that decodes (new codecs) for WAV files? Is it covered by a patent? I know you do for MP3s. Kind of like, you can take a tree branch and whittle it down into a small stick, but you can't whittle the stick UP into a branch. wav, cause it would have to put data BACK that is not there. So you can take a wave and convert it to mp3, and in the process it loses some data. or rather it's pointless as it remains an mp3 file essentially, with a. As expected quality will be the same as the mp3, and re-sampling the mp3 with a high quality wav setting will not yield better results as indicated you cannot put back data that was removed, but you can change formats which I think is what anon27459 wanted to know. In response to anon28062, it is not a true statement to say you cannot convert an mp3 to wav and it is not pointless if you are dealing with something that can only handle a wav format. Which format should I use to burn to CD's? Yes I said records to my computer to eventually save them to a CD. As you may have guessed I am not too IT-literate. The recorded programs are in WAV format.Ĭan you please recommend a software that I could use to locate selected advertisements in the recorded programs and save them in MP3 format. I actually need to capture various advertisements which are broadcasts within each program. I am currently recording radio programs in a computer using a radio card. Could you please tell where i can get more detailed about this so that i can start my programming. actually i m doing my project in announcement system based on arm. there was some that i thought i understood but now i know fully! When you convert an MP3 to WAV, if it's just essentially the MP3 info, why is the file so much bigger? Is there a way that half a wav file becomes smaller in size, not bigger? I am not technically competent, so if you have a way I would appreciate some step by step instructions.Įditing or cutting the wav file I recorded on the flash memory voice recorder makes it bigger! I have the messages on my landline phone. I would like to record telephone messages to a cd or memory stick. By doing so, the file can be used as a master to create other types of audio files (including MP3s), while remaining preserved for direct listening or burning to compact disc (CD).

While the MP3 format is a good fit for portable players, many people continue to store their main digital libraries as WAV files. The MP3 format is a lossy format, however, which means the smaller file size does have some loss of audio quality. Instead, the compressed MP3 format took the audio stage because songs saved in this format are much smaller.

Additionally, these files were not the most practical format to transfer online, especially over slow dial-up connections. Though the cost of hard drives dropped over the years, the format was still too large for portable players with limited flash memory, which would become ubiquitous by the new millennium. One four-minute song could easily consume over 35 megabytes (MB) of space when saved as a WAV. While this format was ideal for sound effects, it had a drawback when it came to music files.

Due to the common roots of these various audio formats, however, the audio files will play on any computer system, IBM or Apple. Apple’s version, known as Audio Interchange File Format ( AIFF), was released in 1988 for Macintosh computers. This file format is based on the Resource Interchange File Format (RIFF), which stores audio files in indexed “chunks” and “sub-chunks.” RIFF is, in turn, based on the earlier Interchange File Format (IFF), established by Electronic Arts in 1985 for use in electronic gaming. Some CD and DVD players can read WAV files when they are saved directly to a disc.

Long before digital audio became a staple, computer users were exposed to the WAV file as an embedded sound file that played a chime-like sound at boot up of the Windows operating system. Microsoft and IBM introduced the format in 1991 for use in the Microsoft Windows 3.1 operating system (OS). A waveform audio file, also known as a wave file, or simply WAV after its extension, is a common type of sound file.
