​
​OPEN AN ACCOUNT AT LOCUS SONUS

​​
​​Live streams for the Reveil broadcast join the Locus Sonus open microphone network (2006- ), and appear on the public soundmap at https://locusonus.org/soundmap/
​​
​​Start by setting up an account. 
​​Go to:
​​Use a basic character set.
​​Your account should be quickly validated and you will receive a confirmation email.
​​Note your stream name (which is also your user/login  name), and password.
​​You can log into your new account at:
​​> Advance configurations to make changes and add information about your stream.
​​
​​ 

​
​CREATE A STREAM PROFILE

​​
​​To confirm your start time  and let us at Soundcamp know you will join the broadcast, please create a short profile  for your stream. Go to:
​​http://streams.soundtent.org/users/sign_up  > Enter your details > ‘Save’
​​
​​Your new stream profile will appear in the list of streams for the broadcast:
​​Each page can include:
​​—  An image
​​— A short description
​​— A long description
​​— An audio clip (optional)
​​— A link to the URL of your stream
​​
​
​To edit your details, go to:
​​Log in, find your stream and click Edit. Make changes and Save
​​
​​Once entered, this will be visible on a web page and will be archived, like this one from 2020:
​​
​
​Streaming time
​​Confirm your streaming window between civil twilight and sunrise on Saturday 2 May (Western hemisphere) and Sunday 3 May (Eastern hemisphere). This is when we will pick up your stream. To find these times for location, go to:
​​or
​​Enter the exact location of your stream and the date (1st or 2nd May 2021).  Note the time of Civil Twilight in the morning and the time of Sunrise. This gives your streaming window.
​​Please enter those in the form.
​​
​
​Saturday or Sunday?
​​Dawn Chorus Day lasts 24 hours. The broadcast travels West from the Greenwich Meridian, (0° of Longitude) starting on Saturday morning. By the time it crosses the International Dateline (180° of Longitude) it will be Sunday. So places in the Eastern hemisphere will join the broadcast on Sunday 2nd May. If  the coordinates of your location on Google Maps are negative, your location is the Western Hemisphere. If they are positive, you are in the Eastern Hemisphere. If  you are  close to the Greenwich Meridian,  near the poles, or in doubt, let us know:

​​
​
​Stream URL
​​To play your stream in the profile page, you need to add the URL of the stream on the Icecast server at Locus Sonus.
​​The URL will be included in the email you received when you signed up. But you might have changed it, for instance by removing the ‘mobile_’ prefix. You can check your up-to-date stream URL by logging into your LS account at:
​​Click Advanced configurations.
​​Your stream URL is shown  in the box near the top  of the page.
​​** If you change  your stream URL, remember to update your stream profile, or the link will break. **

​
​CHOOSE A METHOD — PHONE, LAPTOP, PI

​​
​​

​
​Streaming with a phone

​​
​​
​
​Considerations
​​
​​— Locuscast  is a free app for mobile. It works on iOS or  Android.
​​
​
​— It is probably the simplest,  fastest way to set up a short term stream for the broadcast. 
​​
​
​— Some onboard microphones (eg on  fairly recent iPhones) are excellent. Some are not. But a phone  can  provide a quick and vivid stream. 
​​
​
​—  The audio quality depends on your phone (as well as where you put  it). To get ‘broadcast quality’ audio, you can use an adaptor. 
​​
​
​— Any stream will benefit from  thoughtful placement and wind protection. A piece of synthetic fur or something knitted will stop a good stream being heavily coloured by wind roar.
​​
​
​— Streaming is pretty power hungry. Consider an external battery. In some cases this is eseential eg an iphone with Zoom recorder as USB interface will give a power shortage error without a battery. In this case, choose an adaptor with a USB data connection and and power input point (<) below)
​​
​
​Download Locuscast  mobile app
​​iOS
​​Android
​​
​​Open settings at upper right.
​​Enter your account / stream name and password, adjust quality settings > Done
​​Click Start to start streaming.
​​The clock runs..
​​ 
​
​Connecting an external audio device
​​A portable recorder with the ability to work as an audio interface can connect to an iOS or Android phone with the right adapter. The Zooms do this (eg H1, H4)
​​
​
​iOS
​​You can use an  Apple camera adapter or a clone. 
​​
​​** Choose the one with the additional  charging port.  You will likely need a battery for this approach, as the phone will  probably report  a low power issue if you try to use it to power an external interface.**
​​
​​The Zoom requires a manual button  press to appear as an audio interface (rather than a storage device). Some devices (eg  Mix Pre) may be fiddly to  interface with. Ask  us if in doubt or mail the Locus Sonus streaming list to connect with other  streamers.
​​
​​Once you have an audio interface, you can connect external microphones..
​​
​​
​​
​​You can also connect a studio soundcard this way eg the Focusrite 2i2, which lets you connect mics needing 48V Phantom power.
​​
​​Minus the microphones, that looks like this:
​​
​​
​​
​
​Android
​​
​​You can use an On The Go (OTG) cable in the same way. 
​​
​​Here is a useful discussion, which reports Zooms working well. 
​​
​​** But does this need a power point, as with the iOS adaptor above? ** 
​​
​​It probably depends. With Android there are lots of different phones, so harder to be sure what works and doesn’t. Please experiment and share your findings on the list.
​​
​​The Android version of Locuscast was updated in 2021 in line with the version for iOS.

​
​Streaming  with a laptop

​​
​​
​​Similar to using a phone but might be more convenient, especially from home.
​​
​​Use the pd patch from Locus Sonus, which syncs with your streaming account.
​​Download and instructions from:
​​OR
​​[Likely to be easy and trouble free]
​​Use Broadcast Using This Tool (BUTT). Download:
​​Use these settings:
​​
​​Note:
​​— Your mountpoint could be any name with restricted character set (perhaps use your location name?)
​​— The password is not your account password. Please contact us to get it.
​​— Adjust stream quality, source, etc using the Audio tab in Settings
​​
​
​Syncing 3rd party software with the soundmap
​​
​​BUTT is not linked to the account recognition system at Locus Sonus. When you stream, your stream will appear on the Locus Sonus server as long as your stream name uses basic characters and the password is correct ( <) above ). But it won’t appear on the map (yet)
​​To check it is there on the server as expected, see the streams in list mode:
​​http://locusonus.org/soundmap/ > branching server icon upper right
​​or via the direct URL:
​​To appear on the map, return to the admin page:
​​Login and add the mountpoint from BUTT to the Custom URL field in the form
​​Adjust the position of the microphone icon
​​Enter details on the stream > Save
​​Reload the map and restart the stream
​​
​​

​
​Streaming with a Raspberry Pi

​​
​
​To make a Raspberry Pi Streambox, see Method 4 in the page on methods:
​​
​​Use the links in Recipes to download software from Locus Sonus or Soundcamp
​​
​​Follow the LS setup instructions:
​​** Note an  extra step required to extract streambox software on Linux
​​
​​Use the Streambox web interface  to make adjustments
​​
​
​Watch a video on setting up a stream with a Pi (and other methods)
​​
​​

​
​RUN YOUR APPLICATION AND CHECK YOUR STREAM

​​
​​Start Locuscast, run BUTT or power on your streambox.
​​
​​Your stream appears on the LS live soundmap:
​​
​​You can find it by location or (especially if not in the right place), from the menu available from the icon at upper right. You can also see a list of streams on the LS Icecast server in  list form:
​​
​​To adjust  the location of the microphone icon or add information appearing in the ‘Read more’ section of the soundmap (available by hovering over a mic icon), open the admin page:
​​Log in > Advanced configurations, make changes >  Save.
​​
​​** If using BUTT or another 3rd party app, your stream will be on the server list, but not on the map, as there no automatic synching with your LS account.  To appear on the map, paste the URL of your stream  (available from the server list) into the Custom URL field of the form > Save > Reboot your device.
​​

​
​LISTEN AND  MAKE ADJUSTMENTS

​​
​​Check that your stream sounds the way you want it to, and make any changes needed  to your installation.
​​
​​Consider the location, wind and weather protection, and how the  sounds will be early in the morning.

​Microphones
​​
​​Buy microphones or Primo EM-172 / 272 capsules from micbooster:
​​Make microphones:
​​Simple P48 mod to make Phantom powered mics for USB soundcard eg Focusrite 2i2 2nd Gen
​​More refined PCB by Grégoire Lauvin (also more complicated to make)
​​You can also use any microphones you already have with the USB audio interface > keep dry and use wind shielding
​​To use microphones with Plug in Power (PIP), you need a Pi hat such as Audi Injector or IQ Audio to interface with the Pi. None of these are very intuitive. Ask on the forum:

​ABOUT

​
​Reveil / SC 8

​​OFF GRID
​​OUT SIDE
​​
​​Reveil is a 24+1 hour radio broadcast of the sounds of daybreak, co-produced by streamers around the world on Dawn Chorus Day each year.
​​
​​Reveil follows the zone of intensified and varied sound that circles the earth continuously along the grey line of first light, returning to its starting point after 24 hours without repetition.
​​
​​Sounds produced by birds, amphibians, weather, fish, electromagnetic fluctuations, people, machines, vegetation, transmission artefacts, vibrant matter,* convey the diversity of planetary soundscapes, captured from many specific places and projects. In the process, Reveil brings together dispersed and lesser known ecological projects and practices across disciplines and timezones, in a sketch of an acoustic commons in the making.
​​
​​Streams range from temporary projects in people’s homes to large research networks. Each open microphone adds detail to the mix.
