SMART HOME DEVICES = SAY GOODBYE TO PRIVACY
For years, home automation and home monitor systems have been a nightmare for security and privacy. Hackers love doing smart home hack demos, often flicking lights on and off from miles away, and the patchwork nature of the devices means a setup is only as strong as its weakest link. The data collected by those devices is often some of the most sensitive data you have, leaving smart home device companies under the looming threat of a data breach. These devices can tell when you leave your house, when you fall asleep, and what you cook for dinner. In a fully connected home, almost everything you do leaves some kind of digital trace. And in most cases, that data is spread across multiple companies, leaving lots of opportunities for it to leak out.
SMART HOME DEVICES = SMART SPIES
By now, the privacy threats posed by Amazon Alexa and Google Home are common knowledge. Workers for both companies routinely listen to audio of users, recordings of which can be kept forever, and the sounds the devices capture can be used in criminal trials.
Now, there's a new concern: malicious apps developed by third parties and hosted by Amazon or Google. The threat isn't just theoretical. Whitehat hackers at Germany's Security Research Labs developed eight apps, four Alexa "skills" and four Google Home "actions", that all passed Amazon or Google security-vetting processes. The skills or actions posed as simple apps for checking horoscopes, with the exception of one, which masqueraded as a random-number generator. Behind the scenes, these "smart spies," as the researchers call them, surreptitiously eavesdropped on users and phished for their passwords.
SMARTER HOME MONITORS FOR THOSE THAT VALUE PRIVACY
The Sub Zero Sound Home Monitor System has ZERO external data collection. All your data stays in your home! You can access your home monitor data from anywhere if you know the password, but no one else can. True security and privacy at last.

Techology warning from the FBI.

Hackers can use that innocent device in your house to do a virtual drive-by of your private life.
Unsecured devices can allow hackers a path into your router, giving the bad guy access to
everything else on your home network that you thought was secure. Are cameras and microphones secure?
Is private information safely stored on your computer, or is it being passed around from server to server?

HOME SECURITY DEVICES, Digital Assistants, Smart Watches, Fitness Trackers, Thermostats,
Refrigerators, and even light bulbs are all on the list of potentially insecure devices.

The FBI offers several remedies. They're not all easily enacted:

1. Change the device's factory settings from the default password.
A simple Internet search should tell you how -- and if you can't find
the information, consider moving on to another product.

2. Many connected devices are supported by mobile apps on your phone.
These apps could be running in the background and using default permissions
that you never realized you approved. Know what kind of personal information
those apps are collecting and say "no" to privilege requests that don't make sense.

3. Secure your network, and restrict the information the devices can share.

If you don't want to try to secure your devices, don't say the FBI didn't warn you.


AMAZON'S SURVEILLANCE EMPIRE

Amazon's business model is all about using monopolistic practices to sweep up
and exploit data from our private and public lives. Their products record our conversations,
capture us on live camera feed, identify our faces, and track our movements. Amazon partners
with local police departments to build a nationwide surveillance network. And they contract with
election officials to provide services that allow them to access and store our voter registration and
voting history, including the candidates we voted for. Amazon is a threat to our homes, our rights,
and our democracy. We need to stop them in their tracks.

DANGERS OF AMAZON-POLICE SURVEILLANCE PARTNERSHIPS

In over 600 cities across the country, Amazon provides police departments with
warrantless access to request and store footage from Ring's doorbell cameras.
In exchange, local law enforcement use their platform, social media, and city events
to market Ring products and technology. The surveillance partnerships between police
and Amazon poses privacy, civil liberty, and security concerns. Amazon’s Ring-police
partnership best exemplifies their surveillance empire in action.

Threatens Our Civil Liberties

In the absence of clear policies to govern the use of surveillance data, once footage
is collected and stored, law enforcement can use it to conduct facial recognition searches,
target protesters exercising their First Amendment rights, or share with other agencies like ICE.
Such power without accountability disproportionately impacts black, brown, and low-income
communities already targeted and surveilled by law enforcement. Amazon subverts our
Fourth Amendment rights by giving law enforcement backdoor access to mass surveillance
footage without a warrant.

Threatens Our Privacy

Amazon's Ring doorbell cameras provide footage of millions of American families. They record
everything from baby in their crib to someone walking their dog to a neighbor playing with
young children in their yard—and other bystanders that don't know they are being filmed and
haven't given their consent. These cameras capture and store intimate, personal moments of our
lives that can be accessed by police en masse. It's only a matter of time before the police will have
direct access without request. Devices in Amazon smart homes have no opt-out feature. Recently,
Amazon recently experimented with a feature for 911 calls to trigger Ring doorbell cameras
to wake up and live stream for police use.

PHONE APPS


RECORDER TOOLS
4 TRACKS

Multi-track recorder for songwriters.
Records audio from the phone microphone
or from an external source
via the combination headset/microphone jack.
Accessory input cables and boxes are available
to record live sound microphones, guitars,
various instruments, mixers, or even another mp3 player.

This app comes with 4 tracks which can be mixed down
to a wav file for uploading to the cloud.
Gain control is provided to boost weak sources.
Sound on sound synchronization can be fine tuned
to match various cpu speeds.

Recorder Tools 4 Tracks - Operating Instructions

To record tap a Track button until it says trk* rec, then tap RECORD.
Tapping STOP will stop recording and return to zero.
Each Track button can be set to MUTE, PLAY, or REC (Record).
Except PLAY is skipped if the track has not been recorded yet.
Note that REC is skipped during recording to allow toggleing PLAY/MUTE.
The waveform image can be moved around the screen to see it all.
The waveform image is currently limited to 5 minutes,
but the recording will continue past that.

Setup:

It is recommended to tap PROJECT first (to initialize all variables).
If you have named the project, it will then be displayed.
If not, tap NAME and OK, then tap the text box at the top of the screen.
Now you can type in your projects name, and tap SAVE.
Tapping PROJECT repeatedly will round robin through all 10 projects.

IMPORTANT: If you hear a delay between tracks - Adjust SYNC!
All digital signal processors have a latency, or delay (google latency).
Fast hardware/software can get the delay down below 2 milliseconds,
which is inaudible. Phones are not optimized for audio processing
and have an audible delay which varies depending on cpu speed
and software efficiency, plus apps timeshare the processor.

The SYNC value compensates for the delay, which varies with
the phones cpu speed (and background processes).
The SYNC value is saved in a file when you adjust it
so you need to set it up just once.
If you have a slower phone, first try setting SYNC to 3.


Modes:

1. Normal Mode - Can record any 1 track while listening to other tracks.
The meter displays input level.
Input gain can be adjusted with the fader next to the meter.
Other tracks can be muted if desired.
Track Image shows waveform.
Drag and drop waveform images as desired.

2. Monitor Mode - Listen to Input Source while checking level via meter.
Always plug in a headset to prevent feedback.
Automatic mute occurs when signal level is too high.
Input gain can be adjusted with the fader next to the meter.

3. Mixdown Mode - Records the 4 tracks to a wav file.
Adjust the level of each track after tapping MIX.
Drag and drop the Mix Faders wherever you like.
Tap MIXDOWN to begin recording the hidden file.
At the end of the song, tap STOP and you are ready to upload.
Tap CLOUD to go to the Upload Page.
The file size can be up to 10 megabytes.
Uploading usually takes about a minute, so be patient.
Access the wav file from a computer at Skydrive.Live.com

4. Bounce Mode - Records 2 to 4 tracks to a hidden file.
Adjust the level of each track after tapping MIX.
Tap BOUNCE to begin recording the hidden file.
At the end of the song, tap STOP, then set a track to REC mode.
Finally, tap SAVE and the REC Track will be overwritten.
To cancel, before SAVE tap MODE instead.





















MASTER TRACKS

Multi-Track Recorder, DJ Mixer, Lecture Recorder.

4 Track recorder for songwriters with sound on sound.
DJ mixer with fade in/out, effects, and speed control.
Lecture recorder for long recordings (up to 100 Minutes)

Records audio from the phone microphone or from an
external source via the combination headset/mic jack
with an accessory box (like the Tascam iXZ).
Playback via the headset jack into an amplifier
typically needs a booster (ex. FiiO E6)

Master Tracks - Operating Instructions

4 TRACK Protocol Description:

Each track has a MODE button (trk1-4 play,mute,rec),
with waveform Images beside them. The Images can be dragged and dropped across the screen.
The Meter indicates Record Volume and the vertical Slider adjusts Record Volume.
Pressing the RECORD button will begin recording as long as
a Track MODE button is in Rec mode. Sound on sound recording is
normally done with headphones on to hear other tracks
(Phone Airplane Mode recommended, except for Up/Downloads).


IMPORTANT: If you hear a delay between tracks - Adjust SYNC!
All digital signal processors have a latency, or delay (google latency).
Fast hardware/software can get the delay down below 2 milliseconds,
which is inaudible. Phones are not optimized for audio processing
and have an audible delay which varies depending on cpu speed
and software efficiency, plus apps timeshare the processor.
The SYNC value compensates for the delay, which varies with
the phones cpu speed (and background processes).
The SYNC value is saved in a file when you adjust it
so you need to set it up just once.
If you have a slower phone, first try setting SYNC to 3.


Pressing the PLAY button will play all Tracks that are in Play Mode.
The MODE buttons can toggle Play to Mute and back as desired.
Note that non-existent Tracks cannot be changed to Play and will stay in Mute.
The MIX button will bring up 4 Faders (slider controls) to adjust
individual Track Volume during Playback (or Mixdown),
and the Faders can be dragged and dropped across the screen.
Pressing the PLAY button with one track in Rec Mode will set PUNCH Active,
and the RECORD button is used to punch in and out of recording.

Pressing the STOP(PROJECT) button will Stop
playback or recording and Return to Zero.
When stopped, the STOP button becomes the PROJECT button
which selects the next project and round robins through all projects.
Pressing the PAUSE(MENU) button will pause playback
or recording, and pressing it again will resume.
When stopped, the PAUSE button becomes the MENU button
which allows multiple options to be set on Page 2.

Pressing the FORW button will advance through the song quickly
and can be pressed when Stopped or during Playback.
Pressing the FORW button again will resume playback
at the new Position Mark or freeze it until PLAY pressed.
Pressing the REW button is similar to FORW except in reverse.
Pressing the STOP button will reset the Position Mark to Zero,
so use the PAUSE button and FORW+REW to maintain position.

Pressing MENU then MIXDOWN (on page 2)
initializes the hidden Mix Track.
The Tracks can then be Mixed Down to create a multi-track song.
Start the Mix Down by pressing MIXDWN. Tap MIX to adjust Volumes as the Tracks play.
At the end of the song tap STOP and go back to PAGE 2 to activate MIXPLAY
to hear the hidden Mix Track you just created.
Once satisfied, you can Upload the hidden Mix Track to the Cloud.
Also MIXDOWN can be used to Bounce Tracks to the Mix Track to free up
more tracks for recording. After Bouncing you must go back to
PAGE 2 to COPYMIX to a single track to free up the extra tracks.

Tick Tracks can be created to help you maintain constant rhythm.
The Beats Per Minute is set by the horizontal slider.
The Measure Time is set based on which track you select.


LECTURE Protocol description:

LECTURE Protocol allows tracks to be recorded
one after another (instead of simultaneously) for long recordings up to 100 minutes.
Tracks are advanced automatically after 20 minutes each. Simply press RECORD
and set Gain to keep the Meter near the middle of its range.
End recording by pressing STOP, then press PLAY to listen back,
and use the Track Mode buttons to skip from track to track.
FORW and REW will quickly advance the position in the tracks.
Note that the last track, Track4, can record up to 40 minutes,
even though the image only shows 20 minutes.


DJPLAY Protocol description:

DJ-PLAY Protocol allows tracks to be played
one after another or simultaneously. The individual Track Mode
buttons control when each track will start playback. MARK (position) Mode
allows the Marker to be moved by FORW and REW to set the start Play
Position of a second track while the first track is playing.
The second track can be set to Play before the end of the first track
and faded in with the MIX controls.
Speed up or slow down the music with the slider control.
Effects can be played and new effects recorded.
Note that effect record only lasts 1/2 second, so be quick.

DJ-PLAY protocol can be setup with DOWNLOAD, which saves a song to
the hidden mix track, then COPYMIX to an individual track, and
repeating the DOWNLOAD and COPYMIX for other songs to the other tracks.
Advance to the next Project after 4 tracks to download more songs.
Note that MP3/AAC/etc. songs need to be converted to WAV format
before Downloading (use encoder/converter software on a PC).
To maximize efficiency, recode tracks to 16000Hz Mono PCM (WAV).
Another option is to use RECORD protocol to record songs played
by another source using the phones microphone, or an audio interface box.
Record one song per each track, or one after another song on one track
(recommend 2 to 3 songs per track maximum). Then DJ-PLAY protocol
will allow jumping back and forth from track to track, while using
the Position Mark to skip to the desired start point for each song.
