In May 2020, to jam together with a person over the internet (me on violin and other on guitar etc), I setup JamKazam with colleague in Newcastle including setting up:
router port forwarding and UPnP
audio input device (USB Webcam mic)
audio input device VST EQ filter to stop hiss on Webcam mic
audio output device (earplugs to stop feedback)
This was difficult and took several hours as there were many undocumented features re networking setup and audio settings were difficult to get right that worked and did not have hiss etc or where there was no audio at all due to wrong configuration.
It was remarkable to hear someone in Netherlands playing electric guitar via their audio interface over JamKazam while I played violin via Webcam mic which was hissy and I fixed later with VST EQ plugin via
kvraudio.com an amazing repository of audio plugins both free and commercial.

Arduino chips and wiring.
In July 2017, I visited North Lakes and saw
Google Home AI assistant and Android Watch both good for mobile app I am developing round patient. Google Home integrates with Google Calendar and can switch on and off smart lights etc and answer questions from Google search and play audio and video tracks via Chromecast using voice activation.
Google Home Review
Amazon Alex is a smart home device that allows streaming, ordering online, weather, news, search, setting reminders and making calls that is interacted with using voice. It is integrated with dozens of Internet of Things devices.

Apple Smartwatch has Wifi and apps and can pair to a smart phone using Bluetooth. We plan to develop apps for it.
Best Apple Watch apps to Use
As of March 2012, we plan to install and set up Audio Visual Equipment and Lighting by programming iRuleAtHome iPhone, iPad, iPod Touch and Android cloud-based and wireless technology.
This includes digitally managing home theatres, CCTV security cameras and smart digital houses with smart hand-held devices.
As an example of integrating internet and TV, in April 2013, we setup SONY large screen TVs with WiFI to view YouTube, on-demand movies and other internet content.
As of March 2016, we setup Chromecast dongle on HDMI TV for YouTube video streaming via NBN Wifi. We plan to extend this to other video and audio streaming via Wifi.

Google Chromecast: Whats the Difference Between Casting & Screen Mirroring? Explained w/ Examples
In May 2016, I am exploring
Plex media server for private streaming video and audio and pictures to many devices including mobile, tablet, laptop and digital TV. Plex is a ReadyNAS app as part of the apps developer community, runs on Linux, MacOSX and FreeBSD servers, other NAS, laptops and desktops and is partially open source.
How the Plex Media Server Works - The Basics
Smart TV and Smartphone Audio and Video Streaming
We are exploring live streaming audio and video to Smart TVs and Android Smartphones or Tablets using Chromecast dongle and Android app.
We stream to Android Smartphones and Tablets via Soundcloud.
We stream from Android Smartphones to Windows PC as Webcam using DroidCam and PocketWiFi hotspot.
Streaming Video On Demand for Events
In July 2011, I explored setting up a wifi/ustream video/podcast recording venture with an ethnic church in Sydney CBD. This never happened probaby due to lack of money. IP TV video on demand will be introduced soon via FetchTV or similar. YouTube for backing was included in a very innovative way.
In 2014 we developed Salt Table Helper Mobile App for Science open data competition by Qld DSITIA using groundwater electrical conductivity open data and visiting a cane farm in Burdekin area of Home Hill North Queensland to shoot video. We produced a
YouTube video for the competition using Adobe Premiere from Adobe Creative Cloud monthly subscription on Windows laptop.
CASIO CTK-7200 Demo - keyboard - touch sensitive
In October 2017, we
taught a piano student using a CASIO CTK-7200 electronic keyboard. This has features for pedal, SD card, MIDI, editing data files, line in and out, organ pitch bends, split keyboard and drums. CASIO provides Windows and MacOSX drivers and software to edit sounds.
In November 2019, the
piano student I was teaching bought a KORG KROSS 2 synthesizer workstation, a very advanced synthesizer.
We plan on creating or broadcasting Podcasts of music and online training using Apple iTunes and MP3s for iPhone, iPod, iPad and Android.
In June 2017, we are planning on doing violin digital recording at Caboolture Hub studio.
We can edit your MP3 podcast recording using
Audacity to remove noise and remix.
A Complete Introduction to Audacity
I was in RooRythmics Bush Band in Eastern Sydney Australia as fiddle player and recorded a demo tape with band members in Waverley at
Charing Cross Studio in 1990s. Recording was on demo cassette. Session took whole day.
In August 2013, I visited
QUT Robotronica and 7bit Hero a techno-band played with a live mobile games app animating background of band as they were playing, mixing gaming with music!
Since about 2005, we have been planning to develop audio tracks or story lines for video games for mobile phones or gaming devices. This would include Windows XNA games (XBox360/Windows Phone).
In January 2010, I explored configuring a Linux server to run
Rivendell when attempting to replace obsolete OS/2 system at Rhema FM in Orange NSW. They opted for a Windows system and reentering all the tracks manually instead of automating the transfer using scripts which I could have done easily. As they only had volunteers and very low budget, the community group did things manually to save money making my ideas impossible to implement.
I invest in or rent my own equipment and training so I don't get left behind by Luddites. I then reap the rewards of investing in new technology and opening up horizons in media broadcasting over the Internet with pretty much limitless possibilities to help the world's peoples no matter where they are or what language and culture they have.
In December 2012, I started working on Wordpress audio streaming project using Rivendell and IceCast but it fell through due to project management bungling (job was cancelled but customer kept probing for specs even though no funds were coming in due to job being cancelled).

In 2012 as Webmaster of
Digital Publications Indexing SIG, I have created an MP3, streaming music, audio and ebook library using a digital library system for entertainment, broadcasting or education. This includes audio books for libraries.
Multimedia ebooks including pictures, animation, video and text will be explored and delivered over the internet.
There are a range of media players for various operating systems.
We consult re Network Area Storage and wifi hotspots to store and serve the digital media.
Mobile Educational Apps
In 2014, we created JSON and organised multimedia audio-visual material for a mobile app in Sencha for English as a Second Language (ESL) Bible movie application.
In 1992, I catalogued music CDs in Bowen Library, Maroubra NSW just after I finished my Graduate Diploma Information Management-Librarianship at UNSW. It was a very satisfying job. I got to enjoy snippets of the CDs and saw a music collection being setup properly so people could browse and borrow classical and jazz music.
In 1992, I setup a Mac
Claris Filemaker Pro database of sheet music holdings for Music in Communities Network next door to the Australian Music Centre, The Rocks, Sydney.
In 1991, I catalogued music manuscripts of Australian composers at the
Australian Music Centre, The Rocks, Sydney, NSW as part of my librarianship diploma at UNSW.
In about 1996, as President of Waverley Randwick Philharmonic Society Inc, I licensed usage of sheet music with
VoIP Phone and Video Calls
We use and support Skype and VoIP phone calls and videoing systems over the Internet via ADSL or wireless. This works very cost efficiently in Caboolture and lets us service Sydney, Wollongong, Brisbane, Canberra and other cities far from us at very low cost without being onsite.
It also allows Dwight Walker to provide
online music lessons.
