Audio Magnetic Card Reader

High Qualtiy 2 channels Audio Recorder with Encryption sound fonction Firmware and software is needed. (see picture for size and idea of hardware)\r\n\r\n- High-quality audio recording on a Flash memory 1MB-2MB\r\n Encrypted Sound File output (will need download and decoding software as well)\r\n\r\n- Use different power supplies sources between 2.7-3.7V\r\n\r\n- Size - 7mm * 20 * 1.2mm\r\n\r\n- Adjustable Sampling - from 5 to 24 kHz, \r\n\r\n- Bit analog-to-digital conversion - 16-bit recording saved in WAV-file with compression.. \r\n Voice activation selection (VOX) \r\n- Low Power Current consumption \r\n\r\n-The average current consumption in the recording mode - 18-26 mA, \r\n\r\n- Current consumption in standby mode, start recording IMMEDIATELY when sound is heard. - \r\n\r\n- Current consumption in standby mode, recording pauses VOX - 2-2,5 mA.\r\n \r\n- Current consumption LED display error and exception handling (wrong format or card failure, voltage drop, overflow card) \r\n\r\nWill need PCB laytout, Firmware for encryption as well as audio file compression, high quality sound Chip\r\nVERY important if possible 2 CHANNELS recording into 2 SEPARATES FILES\r\n\r\nPlease bid only if you have done this before.
