    Hello, I have a question.

    Usualy a wav on almost every CD is about 30 to 50MB large (aprox 4 minutes).

    Now just for an example when you create a audio CD from MP3s with a program like Nero, the program automaticly converts the mp3 to wav. But if I already have a wav on my computer that is higher quality and aprox. 130MB large and is still 4 minutes long.

    Will Nero convert the wav to lower quality?

    Thnx

    actually when you create an audio CD the burning software doesn't convert the audio file to WAV, it converts it to linear PCM, known as CDA (CD Audio). WAV is just a windows format of uncompressed audio.

    If your high quality WAV file is the standard CD quality of 16 bit 44.1Khz samplerate, than nero won't convert it to a lower quality. However if you have a 130MB wav and the song is only 4 minutes, I suspect the samplerate is probably higher. Nero will not convert this file. Download dBPowerAMP, and convert the WAV to the correct samplerate, then burn in nero.

    What? OK first things first. CD burning software doesn't convert things to WAV it converts them to PCM. PCM is alot like the WAVE format in that it encodes uncompressed raw audio data (samples). Since this is true you can you can multiply the amount of Kilo-bits per sec. by how many min. the audio file is and come up with about how large the file will be (sample rate is also a factor).

    To answer your question, no, you won't loose any quality going from WAV to PCM unless the WAVE file has a sample rate higher than 44.1 KHz and/or is higher than 16 bits in length (audio proccessing length)!
