    How to Digitally Record Audio Files:

    Needed Materials for Hardware Setup

    1. Original Audio Recording (Tape, CD format, or Live).
    2. Computer (faster will save you more time) with at least 275 MB of free space.
    3. Cable to connect Tape, CD player, microphone, etc. to Computer’s Sound Card.
    4. Sound Recorder/Editor software.
    5. Encoding software.
    6. Web page space.

    Setting Up Your Hardware
    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.

    Now that you have an idea of the hardware setup, follow the directions below depending on the format of your original recording.

    • CD FORMAT: Few people have sound bytes previously recorded in CD format; so if your original recording is in another format, skip to the next section. But, if you have a CD-ROM copy of the desired audio, then you can use a program called a stripper, to “strip” data from the CD and turn it into a WAV file. I have only used a shareware version of Audio Grabber and Audio Catalyst. I am aware of other strippers. Please check the site below for a list and review of shareware versions of other strippers. Once you have mastered the use of your stripper software and produced a WAV version of the audio, then you will be ready to skip to the next section: Noise Reduction.However, you may not need to reduce the noise of your recording if the original was high quality. Please see the following pages for more details on strippers and related software: The “Updated Daily” MP3 Page
    • ALL OTHER FORMATS: First, you will need to locate the connection ports on your originating source and the sound card on the back of your computer. On your originating source, look for some kind of output port, like a headphone receptacle or, even better, an RCA Line Out port. On your sound card look for some kind of Line In port. A microphone receptacle will work, but a Line In port will be better. Once you have done this, then you will need a cable, and possibly some adapters, to connect your source to the sound card. I bought a 6′ cable from Radio Shack that will plug into the “HEADPHONES” receptacle on my tape player and an identical LINE IN port on my sound card in my computer. For you it may take some time at Radio Shack, or a similar electronics store, to find a cable that will match your system, since everybody’s setup may be a little different. If you cannot find a pre-manufactured cable to fit your system, adapters, connectors, and other neat gadgets can be purchased from Radio Shack to adapt a cable to fit your system. Expect to spend between $5 and $10 on this step.

    Recording your WAV File
    Once you have completed your hardware setup, you will need a program to record and edit your audio files. Usually the sound recording software that come with your computer does not support high sampling rates; i.e., they make lousy recorders with few options. I know of three packages designed to make great recordings:

    • Adobe Audition– Adobe® Audition® CS5.5 software delivers the professional tools you need to make your video and audio productions sound their best. Handle a wide range of audio production tasks efficiently, including recording, mixing, and sound restoration.
    • Gold Wave  – GoldWaveis a highly rated, professional digital audio editor. It’s fully loaded to do everything from the simplest recording and editing to the most sophisticated audio processing, restoration, enhancements, and conversions.
