TSP (Texas Soundmap Project)

Screen Shot 2016-08-20 at 12.49.55 PM.png

The central idea of this project (still in the works) is to map out Texas’ acoustic history and diversity.

Materials presented here come from three main sources:

1: Recordings from sound archives.

Cushing Memorial Library & Archives, Texas A&M University

Dolph Briscoe Center for American History, The University of Texas at Austin

Alan Lomax Collection, Association for Cultural Equity

East Texas History, Sam Houston State University


John, Ruby, and Alan Lomax recordings [1933-1948]

William A. Owens Recordings [1938-1942]

Oral Histories 

2: Recordings from personal collections.


Leonardo Cardoso Collection

3: Collaborative work with Texas A&M undergraduate students.

Students are organized into groups and work together to learn about the performance from different angles. The tasks each group has to complete include:

  1. Field recording: students should register a representative excerpt  of the performance.
  2. History of the performance: when and how did the performance start? What groups were involved? Has it changed through the years? If so, how?
  3. Participant observation: students have to attend the performances and describe their experience.
  4. Performance analysis: how is the event structured? Is there a narrative? Who are the performers?
  5. Spatial elements: where does the performance take place? How does the space help to shape the performance?
  6. Interview: students have to talk with someone directly involved with the performance.

Sounds from the Street Protests in Brazil (June 2013)


Protesters on Paulista Ave. São Paulo. Source

In the last weeks street protests in Brazil have erupted not only in São Paulo and Rio de Janeiro, but also in small towns across the country.

What was initially a march against bus-fare increase in São Paulo became a much broader – multi- or non-partisan – protest against corruption and millionaire investments in soccer stadium infrastructure in preparation for the 2014 World Cup. Many Brazilians perceive this as exorbitant spending, a shocking contrast with lack of public security, deficient education and health system, and unreliable public transportation they have to face everyday.

You can learn about the protests here, here, and here.

Here is a collection of sounds from the protests. Please help me expand this audio collection!

Sound and urban change: “sounds of nature” and upscale life in Austin, Texas

“The Triangle”  in 2011, when I made the recording.

“Male frogs call to attract females for mating and to defend territories from rival males. Female frogs of some species prefer lower-pitched calls, which indicate larger, more experienced males. Acoustic interference occurs when background noise reduces the active distance or the distance over which an acoustic signal can be detected. Birds are known to call at a higher pitch or frequency in urban noise, decreasing acoustic interference from low-frequency noise. Using Bayesian linear regression, we investigated the effect of traffic noise on the pitch of advertisement calls in two species of frogs, the southern brown tree frog (Litoria ewingii) and the common eastern froglet (Crinia signifera). We found evidence that L. ewingii calls at a higher pitch in traffic noise, with an average increase in dominant frequency of 4.1 Hz/dB of traffic noise, and a total effect size of 123 Hz. (more…)
