Freedom advocates who are interacting with the government frequently find government servants they talk to to be unfriendly, uncooperative, and inclined to attempt to exercise authority that neither the law nor their delegation of authority order confer upon them.  To protect ourselves from such abuses, it is prudent to record all telephone conversations we might have with such criminal government servants.  This article will describe in detail the tools and techniques for recording telephone conversations using your computer.  The resulting recording takes the form of an MP3 file, which you can play on your computer or any portable MP3 player.

1.  Telephone Recording Cable

Radio Shack makes an inexpensive telephone Recorder Control, Catalog Number 43-1237.  This cable hooks in series with your telephone and has an audio output connector that hooks up to the Microphone Jack on your computer.  You will first need to buy this cable.

2.  Buying and Configuring Recording Software

In writing this article, we surveyed and tested at least ten different sound recording computer programs.  There are many ugly and ineffective products out there.  Far and away the best, most capable, cheapest, and easiest to use program we tested is one called Audio Recorder Pro from  EZ SoftMagic available at:

Below is a screen shot of the program so you can see what it looks like:

Telephone Recording

This program has a simple interface, costs only $29.95, and will produce MP3, WAV, and OGG files.  It can record from any audio source that your computer has, including the following:

  1. Telephone Modem
  2. Microphone Jack
  3. Aux In jack
  4. Line In jack
  5. Wave generator
  6. CD audio
  7. DVD video
  8. Television card (if you have an ATI All-InWonder Radeon TV Tuner video card, for instance)
  9. Internet Radio
  10. Real Audio (RM files)
  11. Microsoft Media Player or Real Media Player web listening.

The program also has some other very handy features that we are sure you will like:

  1. Runs in the system tray so it is always ready to record at a moment's notice if you are using the telephone, for instance.
  2. Has a "Mini mode", so that it uses a minimum amount of screen space when active.
  3. Has an "Auto Record" mode that acts like a "vox", whereby silence is removed from the recording to reduce file size.  You can set the audio threshold that will trigger resumption of recording.  This allows you to automatically record a whole day's worth of phone calls with a very small file size.
  4. Records in several formats, including MP3, WAV, and OGG.
  5. Converts between all the different audio formats it supports.  This can be very useful if you want to compress an audio file for internet downloading while minimizing the loss of quality inherent in the conversion process.

You will need to buy and install program.  It has a registration key that allows you to try it for free before you buy it.  Old registration numbers work with later versions of the program as well.  VERY GOOD!

3.  One- and Two-Party Telephone Recording Law

Laws relating to the permissibility of telephone recording vary from state to state.  If you are calling someone within your own state, the law of your state prevails.  When you call someone in another state, federal law prevails.  Laws on telephone recording are classified using one of two names as follows:

  1. Two-party state: both parties must be informed of the existence of recording and give their explicit consent.
  2. One-party state: only one party to the two-way conversation needs to be aware that recording is being done and needs to give his or her consent.
WARNING:  In One-Party states, it is considered a crime to record a telephone conversation if the other party is not informed in advance and does not explicitly consent to the recording.  It is therefore very important that you know the law BEFORE you attempt to record, and especially before you attempt to get your tape recordings admitted into evidence in a legal proceeding.

Below is a listing of the classification of telephone recording laws, by state.  Because these laws change frequently, you might want to double-check yourself.  If you find error in the table below or would like to add "Applicable Statutes" that you have verified yourself, please send us an email revealing the results of your research so we can add it to the table:
