Hidden Recording Devices

The recording or storage of the audio can be done through an integrated electret mic or via any line out or RCA port of an audio reproducing device.

However since the IC is a low bit device does not support Hi-Fi recording rather low quality music. The sampling rate or the frequency response is limited to just 8 kHz max that's pretty ordinary if we compare it with the specs of modern Hi-Fi equipment. Nevertheless, mobile voice recorder chip, the IC is a stand alone device which does not depend on any external circuits, just plug it in, and it starts recording whatever voice data is fed across its input pins. It's a 28 pin IC which can be very easily and quickly configured for getting the required results by adding a handful of common passive electronic components.

For example pin 28 and pin 27 are assigned as the trigger inputs for initiating playback and recording functions. The IC also has appropriate visual indication options which provide the user with instant information regarding the position of the circuit. The LED at pin 10 stays illuminated for so long the audio is being played, indicating mobile voice recorder chip "busy".

The LED at pin 22 indicates through rapid flashes regarding the playback or recording modes of the IC. The input data is normally picked from the mic which is appropriately connected across the pins 17 and 18 of the IC. The sampling rate of the IC can be set as per the user preference. Longer periods would also mean lower voice quality while shorter periods of recording spec will produce relatively better sound processing and storing.

The audio output may be derived across pin 14 and ground which must be terminated to an audio amplifier so that the data can be heard with proper volume. The IC ISD is a device which features a single chip audio message recording and playback facility, and is able to retain the audio message in it infinitely even while the chip in the un-powered state.

This also causes the chip to go into a power down condition or in the standby condition. In the PLAY E or edge activated mode, a single press and release or a momentary press of the button will initiate the playback of the recorded clipping through the speaker, and will end as soon as the internal EOM end of message signal gets activated.

The PLAY L mode is activated when the attached button is pressed and held pressed without releasing it. The audio mobile voice recorder chip now continues as long as the button remains mobile voice recorder chip, or as soon as the internal EOM is activated. Keeping the button permanently pressed will cause a higher current consumption of the IC.

The FT input signal is responsible for controlling the feed through mode of the chip. In mobile voice recorder chip to be initiated the feed through mode, the pinout FT is held at the positive Vcc logic, while the REC, and the PLAY buttons are at low logic or with their buttons in the deactivated positions.
