Audacity

Audacity is a free software, cross-platform digital audio editor and recording application. It is available for Windows, Mac OS X, Linux and BSD. Audacity was created by Dominic Mazzoni while he was a graduate student at Carnegie Mellon University.

Inputs and trace's reports

We collect 2 traces of Audacity's allocation when doing:
  1. Start the program => report input 1
  2. Import an MP3 song (5.4mb), cut some seconds of song and export as MP3 => report input 2
You can find all MallocLab's traces for Audacity here.

Allocator's configurations

  1. BSA => Original BSA with page allocation and alternate split side (AS)
  2. TLSF => Two Level Segregate allocator
  3. BSA-- => BSA with no split or coalesce and no AS
  4. BSA++ 10 => BSA++ with no AS, popularity index threshold 10
  5. BSA++ (npa) 10 => BSA++ with no AS, no page allocatione (npa), popularity index threshold 10
  6. BSA++ AS 10 => BSA++ with AS, popularity index threshold 10
  7. BSA++ AVG 10 => BSA++ with no AS, average popularity threshold 10
  8. BSA++ AVG (npa) 10 => BSA++ with no AS, npa, average popularity threshold 10
  9. BSA++ AS AVG 10 => BSA++ with AS, npa, average popularity threshold 10
  10. BSA++ VAR 345 => BSA++ with no AS, popularity index threshold >= 15, variance popularity threshold 345
  11. BSA++ VAR (npa) 345 => BSA++ with no AS, npa, popularity index threshold >= 15, variance popularity threshold 345
  12. BSA++ VAR AS 345 => BSA++ with AS, popularity index threshold >= 15, variance popularity threshold 345
Some of these allocators have been tested with different threshold: In this page we show only the winner for each type of allocator's configuration. Read BSA or BSA++ description in order to understand all features listed above.
