LISNR is comprised of Tone Profiles and Tone Types. Please see below for an overview:

Tone Profiles -

  • Standard: Optimized for reverberation and increased reliability. Typically used for Proximity Engagements, Broadcast and Second Screen implementations.
  • Compression: Optimized for frequency range restrictions. Typically used for FM Radio and Audio Streaming implementations.
  • Precision: Optimized for closed distances. Typically used for Authentication, Payments, Access, and Security implementations.

Tone Types - 

  • ID Tones: Created via the LISNR Portal or API. This tone type is a reference to an ID that is associated with a piece of curated content.
  • Text Tones: Broadcasts from the device via the SDK or generated via the API. Contain ASCII Character Set at a 255 for Standard and Compression Profiles. The Precision Profile can carry a maximum of 3000 bytes.
  • Data Tones: Broadcasts from the device via the SDK or generated via the API. Contain raw binary up to 255 bytes for Standard and Compression Profiles. The Precision Profile can carry a maximum of 3000 bytes.
