Shairport Sync Details:
Shairport Sync is an AirPlay audio player which plays audio streamed from iTunes, iOS devices and third-party AirPlay sources such as ForkedDaapd and Airfoil.
Audio played by a Shairport Sync-powered device stays synchronised with the source and hence with similar devices playing the same source. This allows for synchronised multi-room audio on multiple devices.

AirPlay device name:
When searching for an Airplay device, select Shairport-Sync on DietPi

Stream from Android:
https://play.google.com/store/apps/details?id=eu.airaudio&hl=en_GB

Stream from iPad/iPhone
https://support.apple.com/en-gb/HT204289

Stream from a Windows/Mac PC:
Airfoil is an application that will let you stream audio playback directly to any Shairport Sync device. Press play on your favourite music player (eg: winamp/spotify) and click the speaker next to the DietPi device.

Audiophiles - Master music in realtime
By using a PC + Airfoil, you can master the music in realtime using the PC's CPU. This will allow all your shairport sync devices to sound even better without any performance hit on the device.
FuzonMp3 is a lightweight music player coded in c++ that sounds "as it should" and supports VST plugins. iZotope Ozone 5 is highly recommended for audiophiles.


Multiple Shairport devices / Change Shairport-sync Name:
If you are planning to use multiple Shairport devices on the same network, please make sure the hostname of each device is unique. The hostname will also effect the shairport-sync name.
This can be completed in dietpi-config > Security Options > Change Hostname.

Soxr interpolation:
Soxr interpolation will improve the output audio quality on Shairport. However, it is extremely CPU intensive.

Enable Soxr:

Code: Select all

sed -i '/interpolation = /c\interpolation = "soxr";' /usr/local/etc/shairport-sync.conf
dietpi-services restart

Disable Soxr:

Code: Select all

sed -i '/interpolation = /c\\/\/interpolation = "soxr";' /usr/local/etc/shairport-sync.conf
dietpi-services restart

If you have choppy playback using Soxr:
Increasing the shairplay-sync process priority (nice) may resolve the issue.
- Run dietpi-nice from the terminal
- Scroll down to and select 'Shairport Sync' then press enter
- Scroll up and select 'Nice : -20 (Highest priority)' then press enter.
DietPi will then automatically apply and set the nice level.

If the choppy playback continues, the CPU is most likely is insufficient for the processing required for soxr, and, should be disabled.

EmonPi:
Turn your Raspberry Pi into a energy usage monitor with web interface.

The DietPi optimized installation for EmonPi is aimed at users who want the following:

• Ultra lightweight alternative installation to the official EmonPi image, with all the optimizations and features of DietPi. Allowing additional uses for your RPi device (eg: Owncloud server): Htop image of RPi Zero @ 700mhz, running our EmonPi installation.
• Realtime and historical energy usage statistics uploaded to the emoncms.org cloud, viewable from a web browser and the Android App, from anywhere in the world.
• Use an existing RPi, or, do not wish to purchase the full EmonPi package (eg: case).
• Comfortable attaching the EmonPi to your Raspberry Pi GPIO. No soldering or wiring is required.

The DietPi installation does not support:

• RF transmission. RF receiver (sensor nodes) is supported (eg: EmonTX/EmonTH)
• EmonPi LCD screen.
• Local emonCMS webserver on RPi. All emonPi data is sent to emoncms.org cloud.

Requires:

• 1x EmonPi PCB - Order one here: Select Assembled PCB Only - No Enclosure, all other items to none (£59). Image of what you will receive. This installation also supports the optional temperature sensor, but its not required.
• 1x Raspberry Pi (any model)
• 1x Good quality Raspberry Pi PSU - (5v 2amp). The EmonPi does not need its own power supply. It will draw power directly through the GPIO's on the RPi.

Webserver Preference System:

What is "Webserver Preference System"?
The DietPi webserver preference system allows you to choose your favourite webserver for use in DietPi installations.
When you select any software for installation that requires a webserver, DietPi will automatically install, configure and optimize your chosen webserver preference. DietPi will also install Mysql/Sqlite as required, depending on your software selections. Basically, you will never need to manually select/install a webserver stack again. DietPi will do it all for you.

Which Webserver is right for me?
Apache2:
- Memory use = High | Multithreaded = Yes
Feature-rich and popular. Recommended for beginners and users who are looking to follow Apache2 based guides.

Nginx:
- Memory use = Medium | Multithreaded = Yes
Lightweight alternative to Apache2. Nginx claims faster webserver performance compared to Apache2. Ideal for medium-high traffic situations where Lighttpd will suffer.

Lighttpd:
- Memory use = Low | Multithreaded = Optional - Some drawbacks
Extremely lightweight and is generally considered to offer the "best" webserver performance on Linux for SBC's (single board computers). Recommended for users who expect low webserver traffic and/or personal use.
Although the DietPi installation of Lighttpd is set to single threaded, do not be put off by this, in low usage scenarios (<10 users) it will still outperform Nginx and Apache2.

Multitheading is supported by Lighttpd and can be enabled in the configuration file:

• Edit the file /etc/lighttpd/lighttpd.conf
• Add the entry (change 4 to your total core count)

  Code: Select all

  server.max-worker = 4

• Restart services

  Code: Select all

  dietpi-services restart

What software will trigger a webserver installation?
If you select any software in dietpi-software for installation, that requires a webserver to function.
Examples:

• PiHole
• Ampache
• Owncloud
• DietPiCam

I only want to install a LAMP stack, what should I do?
Unless you specifically need a webserver stack, it is recommended that you allow DietPi to install webserver stacks automatically. This will ensure compatibility and stability on your system, for the webserver choice you have made.

Where can I change the preference setting?
Run dietpi-software and select Webserver Preference from the menu. This setting can NOT be changed, if an existing webserver is installed on the system.
