Inputs and trace's reports
We collect 2 traces of Audacity's allocation when doing:
- Start the program => report input 1
- 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

Allocator's configurations
- BSA => Original BSA with page allocation and alternate split side (AS)
- TLSF => Two Level Segregate allocator
- BSA-- => BSA with no split or coalesce and no AS
- BSA++ 10 => BSA++ with no AS, popularity index threshold 10
- BSA++ (npa) 10 => BSA++ with no AS, no page allocatione (npa), popularity index threshold 10
- BSA++ AS 10 => BSA++ with AS, popularity index threshold 10
- BSA++ AVG 10 => BSA++ with no AS, average popularity threshold 10
- BSA++ AVG (npa) 10 => BSA++ with no AS, npa, average popularity threshold 10
- BSA++ AS AVG 10 => BSA++ with AS, npa, average popularity threshold 10
- BSA++ VAR 345 => BSA++ with no AS, popularity index threshold >= 15, variance popularity threshold 345
- BSA++ VAR (npa) 345 => BSA++ with no AS, npa, popularity index threshold >= 15, variance popularity threshold 345
- 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:

winner for each type of
