Serial Kickstarter entrepreneur and project creator Patrick Thomas Mitchell has this week launched his 15th Kickstarter campaign to raise funds to take his new Arduino compatible high quality audio recording and playback module into manufacture.
The Canadian-based electronics expert has created the new development board to provide an easy way to record and playback up to eight sound snippets with over 11 minutes of storage space available for your needs.
The board can either use your PC or your voice and more information about the new Arduino audio board can be learnt from the promotional video embedded below. Patrick explains more about the new audio board.
Meet the Production-Ready Arduino Compatible HQ record and Playback Audio Module! With ease, you can record and playback up to eight sound bytes using your own voice, or PC. There is an on-board microphone, and an audio input, so that you can record sound bytes coming from an external source, such as the audio output line from your PC or Mac! You can also use the on-board audio output jack to connect to your own amplifier/speaker set!
This unit has a maximum recording time of 680 seconds, and a minimum recording time of 341 seconds. There is a sampling frequency VS recording time relationship. The shorter the total recording time, the better the playback audio quality is. This sampling rate is determined by an on-board resistor, and you will have the option of choosing your total recording time in the survey at the end of this campaign. You will also have the option of not having a resistor placed, so that you an choose on your own when your reward arrives.
Using two on-board headers, you can select between single message mode, 2-message mode, 4-message mode, and 8-message mode. In these modes, your total recording time is divided by the number of total messages that you’ve selected. for instance, if you are in 8-message mode, your total recording time is divided by eight. If you have a total recording time of 680 seconds, then each message has a maximum recording time of 85 seconds when in 8-message mode.
Alternately, if your total recording time is 680 seconds and you are in single message mode, then your single message can be the full 680 seconds in duration. You can change your message mode selection before power up as you see fit, but if you change from 8-message mode to any other message mode, then previous messages will be re-recorded over.
