- Streaming Audio
"What is this all about?" Well,
this page describes a procedure that enables you, a web page
designer, to either record or copy audio files from cassettes or
CDs and place them on your web page, available for downloading
and streaming. This procedure will provide a web-surfer the
opportunity to download high quality audio files and listen to
them with a free player. A second option can also be provided
that would allow someone to listen to the audio file
immediately, similar to streaming audio, such as Real Audio.
Digitally Record Audio Files
Depending on the type of recordings that you wish to make,
your setup may vary from mine; however, the basic setup will
remain the same. Each setup will have some kind originating
audio source, such as a tape player, CD player, Live microphone
output, etc. This source will need to be connected to the input
of your sound card on your computer by way of a cable, possibly
using some adapters. Finally, you will need recording software
to actually record the audio.
Noise and Filter Audio
Directions are provided here for using CoolEdit 96 to digitally
reduce background noise from Audio files. If you are just learning
this process, then you may want to jump ahead to the Encoding
step to simplify the task. Also skip to the Encoding step if you
are satisfied with the quality of your recording. However, please
note that background noises do become amplified during the encoding
process. So, your finished product may be unacceptable if the
WAV recording was of marginal, or tolerable quality. Unfortunately,
most people will need to do some kind of noise reduction. So,
use these directions to help walk you through this process, and
be sure to check the Help info about its noise Reduction feature
that comes with CoolEdit. A lot of good information is presented
there, which I have not duplicated here.
The next major step is to compress that whopping 250 Mbyte WAV
file into a 6.5 Mbyte file, or maybe even smaller 2 Mbyte file.
How do you such wonderful things? Simple, use either a MP3 or
VQF encoder. You may be asking, "That sounds nice, but which one
should I use - MP3 or VQF, and what's the difference?". That's a
good question. Here's a few thoughts to help you decide.
Audio Web page
If you have come this far, then you have accomplished the most
difficult part. If you already have your own web page, then you
have probably done this next step: putting the file on the
Internet. To do this simply upload the audio file to your web
page and provide an appropriate link for someone to download the
file. Check out my site for an example that allows you to
pseudo-stream MP3 as well as download them. You might
encapsulate your files into a ZIP archive, since it is much
easier to download ZIP files in some browsers.
