Release notes (v1.2.9)

ISiS v1.2.9 (bug fix)

- avoid python exception in ISiS due to missing values in F0 contours in voiced segments. These missing values are rare but cannot be avoided completely during automated database construction.


(Database files have not been changed, please use those from release v1.2.7)

Release notes (v1.2.8)

ISiS v1.2.8

- added command line option --env_transposition_fac, configSynth transposition_env_exp: more natural singing quality by means of dynamic envelop transposition,
- faster synthesis (about 10-30%) byt means of improved FFT library and pulse parameter cache,
- signficiantly reduced memory requirement: now allows synthesizing very long sogs with constant memory,
- support storing of, and resynthesis from semi-symbolic XML files for F0 and loudness contours,
- added progress indicator to the pulse generation phase that may last rather long (30-80% of song duration).

Changes
=============

Software (v1.2.7)
----------------
- improved error reporting in Max ISiS, most of the errors are now visible in the log file,
- fixed a bug resulting in occasional clics in front and after voiced segments
- fix a bug that lead to failure for very short voiced or unvoiced segments in the singer database,
- fixed a problem in the voiced synthesis when transposition (in cents) decreases to very small (negative) values,
- support more efficient envelope representation in the singer database,
- reduced package size,
- more robust installation scripts.

Database (v1.1.0):
--------------------
(these databases do not work with ISiS v1.2.6)
- changed envelop representation leading to a significantly smaller database.
- improved robustness of installer scripts.

v1.2.6

Mac OS X, Linux
