Introducing the New AEM-40 Audio Evidence Manager Phi Tech Part Number 9000-074

Phi Tech's new AEM-40 Audio Evidence Manager is a sophisticated, state-of-the-art digital system designed to give agents the ability to quickly redact irrelevant passages from audio evidence. No altering of the recording occurs. The redacted segments are still contained in the memory, but the system automatically skips over selected passages and continues playing audio beyond the redacted segments. This is convenient for presentation of audio evidence without the fear of irrelevant or inappropriate dialogue being introduced in a courtroom setting.

How it works

The AEM system utilizes the latest in digital recording techniques, allowing for CD-quality recording using MPEG compression standards. The information is recorded on a removable "flash" memory card. The data stays on the memory card for as long as needed; then the card can be erased and reused.

Audio is transferred from the original media (tape, DAT, etc.) to a solid-state PCMCIA memory card, barely larger than a credit card. Transfer can be made via audio inputs or direct digital code (S/PDIF) from a DAT or other compatible digital source.

 

Redaction points are created and edited with the front panel keys. A menu-driven display and softkey arrangement provides for accessing the unit's many functions without a confusing array of controls.

The continuous-rotation shuttle control and a softkey menu-driven GOTO command provide for instant access to any point in the recording. Headphone jacks are provided for private listening.

Redaction is accomplished by selecting the start point and an ending point of a given audio passage. As the unit is playing, it will automatically skip over any audio information within the range selected, and instantly begin playback of the audio beyond the redacted segments. An internal beeper alarm indicates when a redacted point has been encountered and skipped. Note that the audio is not removed from the recording — only skipped over.

The redact function can be disabled, allowing the user to play the entire recording. When the redact feature is disabled, the operator is warned that any audio to be played will not be redacted.

Redaction points and other operating information unique to the recording are stored on the flash memory card along with the audio. With this feature, each card will retain its programmed skipover points, eliminating the need to re-enter the points each time the card is removed and reinserted.
