This list of digital tools and platforms for creating sound walks updates a list we compiled for a British Library blog, that complemented the Exploring with Sound Walks event in the run up to Sound Walk Sunday in 2019.
As we continuously receive individual requests from creatives, asking what are the best digital tools for creating a sound walk, we decided it was time for a more elaborate list describing the right tools for creating your own sound walk.
However, as these lists are never exclusive, complete, nor definite, please send us additions, comments, and suggestions, as well your views on any of the tools below.

We’ve grouped locative media software in six categories:

• Recommended and tested for sound walk creatives
• Audio guides and audio tours
• Locative maps
• “Hacked” hiking software
• Virtual sound walks
• Build it yourself

Recommended and tested for sound walk creatives 

If you have the objective to realise a more creative sound walk, we are currently aware of four open access platforms for creatives working with sound, that are also low budget or free, one platform that’s in beta, and one that is planned for release in 2021.
They offer easy-to-use online editors and include advanced sound features, such as layering. You upload your own recordings, together with text and photographs, and the sounds are available via an app, or web app, for those consuming your work, walkers. We recommend the following excellent platforms, which we have personally tested, both as creators and users.

Echoes

Echoes Creator is an easy tool to quickly upload audio, images, and text, to geolocate and layer them on an online map, and to publish them for the world to hear. You need only to construct shapes on a map, which then trigger content when your listeners physically walk ‘inside’ them.
Works with an app.

Free, with additional paid plans.

Locosonic

Locosonic describes itself as being designed for creating “movies for your ears”. Locosonic links sounds, music, and stories to a location. The editor has advanced tools for sound artists and musicians, but as well easy features for beginners. It includes a built-in interface to the Freesound database, so you can create sound walks without your own recordings; just search, browse and use more than 100.000 sounds published under permissive licences!

Free for sound walks up to 30 minutes. 

Sonic Maps

At the core of the SonicMaps platform is an easy to use online editor, both for beginners and advanced users, with plenty of features. The sound walks are accessible via a (web)app as a regular sound walk, but as well in a desktop map mode. Sonic Maps also offers the facility to create locative soundscapes on-the-go during your walks, and provides analytics, text-to-speech, and embedding of sound maps in your own blog or website.
Works as an app and as a web-based app.

Prices start at 36 euros for a 3 month plan.

Radio aporee

Radio aporee – miniatures for mobiles is a platform for creating sound walks, and has been around for about a decade. It is a very basic tool, but easy to use for beginners, and for sound artists that prefer it simple.

Another new piece of software is Gesso Creator Tool, which allows you to create linear and non-linear audio walks- by dropping pins on a map.

Audio guides and audio tours

“Hacked” hiking software

Even with plenty of more appropriate services available as mentioned above, “hacked” use of hiking and running apps remains popular among walking artists and creatives. These kinds of platforms allow geo-blogging (of photographs, videos and texts) and GPS-tracking of your walks at the same time.

Virtual sound walks

PlaceCloud

Placecloud is a straightforward platform which allows you to record stories and bits of knowledge about specific places, so that anyone can listen to them as they explore the world, physically or remotely. These ‘viewpoints’ are typically harvested from books.

Build it yourself 

The main disadvantage of most of the above mentioned tools is that they are not individualised and only provide standard features and design that may not fit your project quite like you would like them to. Your creative result is dependent on third party platforms (that may cease to exist) and of external hosting of your contents and data (with the risk that these may be used for other purposes in the future or be lost).
So you could go all-out and choose to build your own platform, as there are tools that allow this, even for beginners.

ARIS (legacy)

ARIS is a user-friendly, open-source platform for creating your own mobile games, tours and interactive stories, suitable for beginners.
