This app tries to identify the file type using the "magicnumber"contained in the first few bytes (similar to the Linuxutility withthe same name).In addition, clicking on a file opens it with theassociatedprogram.File types:7-zip archive dataApple QuickTime movieASCII textAVI databzip2 compressed dataELF executableEPUB ebook dataFLAC audio bitstream dataGIF image datagzip compressed dataHTML documentIFF dataJPEG image dataMacromedia Flash dataMacromedia Flash VideoMatroska dataMPEG mp3 dataMPEG mp4 dataMS-DOS executableMS-Office documentOgg dataPC bitmapPDF documentPNG image dataPostScriptRAR archive dataRealMedia fileStandard MIDI dataTIFF image dataTracker moduleWAVE audio dataXML document textzip archive data

Please note: There is also a demo version (BT mic 1m). Checkthisfirst! Do not buy this app, if the demo doesn't work!You want to use a Bluetooth headset's microphone? Butalthoughthe headset is connected and phone audio is ckecked intheBluetooth settings, yet the phone's internal microphoneisused?This app activates the Bluetooth microphone which is then usedbyall applications instead of the phones's internal microphone,aslong as this app is running in the background (symbol instatusbar).After this app is terminated with the back key, thephone'sinternal microphone gets reactivated.

A "noise light" is similar to a traffic light.It makes the colors green, yellow and red from different soundlevels (and similar to a traffic light, green means "OK", red means"ALERT", and yellow is the transition state).Note that this app is NOT a calibrated sound level meter, and istherefore NOT appropriate for professional use.You can adjust the thresholds for "Yellow" and "Red", dependingon your personal taste.Also adjustable is the response time so that a level change doesnot lead to a color change immediately. Only a certain duration oflevel changes lead to color changes. This prevents single peaks ofnoise from triggering color flicker."Red" can trigger an alarm using Text to Speech with text youcan edit in settings, or by playing an audio file from SD Card. Youcan set a fixed volume, or use the media volume.A click on the display (or optionally rotating it) shows somestatistics.There is also a log-file option with the possibility tovisualize the recorded data as diagram (when the display isrotated).The maximun recording time is 10 hours. The log file (log.csv)is located in the directory "Noise Light" on the SD Card and isoverwritten each time the app is started. As an alternative,several log files (date-time.csv) are also possible.In addition log files can be processed by programs like"Excel&Co".(More keywords: noise measurement, noise level, school,classroom, silence, quiet)

PLEASE NOTE: Requiresadditionalhardware!This app is only interesting for those who can programamicrocontroller with ADC and serial Bluetooth module (e.g.RN-42).Starter version, runs full-featured, but only 5 times. Findthefull version here:http://play.google.com/store/search?q=pub:hdopThis app reads a value via Bluetooth. This can be a voltage,atemperature, a pressure or whatever. This value can bedisplayed,observed and recorded.The observation method is similar to a traffic light. Itmakesthe colors green, yellow and red from specific value ranges(andsimilar to a traffic light, green means "OK", red means"ALERT",and yellow is the transition state).You can adjust the ranges for "Green" and "Yellow", dependingonyour requirements. Tests are as follows: Value within greenrange?Display shows green. Else, value within yellow range? Displayshowsyellow. Else, display shows red and - if enabled - an alarmistriggered.Also adjustable is the response time so that a value changedoesnot lead to a color change immediately. Only a certain durationofvalue changes lead to color changes. This prevents singlepeaksfrom triggering color flicker."Red" can trigger an alarm using a siren (plus vibration),usingText to Speech with text you can edit in settings, or byplaying anaudio file from SD Card. You can set a fixed volume, oruse themedia volume.Rotating the display starts a special display mode, whichisconfigured in settings: You can multiply the "raw" value byafactor and you can add an offset. The number of decimal placesaswell as the digit size are adjustable. Finally, you can add aunit(e.g. "Volt") and toggle min/max display. Optionally, thedisplayedvalue can be read out at regular intervals.A click on the display shows some statistics.There is also a log-file option with the possibility tovisualizethe recorded data as diagram (when the display isrotated).The maximun recording time is 10 hours. The log file (log.csv)islocated in the directory "BT Multi Monitor" on the SD Card andisoverwritten each time the app is started. As an alternative,severallog files (date-time.csv) are also possible.In addition log files can be processed by programslike"Excel&Co".Bluetooth device selection: The selection can be limitedtodevice names containing a particular string, defined insettings.If only one device is available, it is selectedautomatically.Technical info- Bluetooth profile: SPP (Serial Port Profile)- Protocol: ASCII (human readable).The program sends a '?' (0x3f) to make request for a 12Bit ADCvalue(0... 4095). Then the program expects 4 decimal digits tobereturned (timeout 1s).
