< h3 > < br > < b > Known Issues with This Release< / b > < / h3 >
< h3 > If you notice an issue with this release < b > not< / b > mentioned below, please contact ecodis or a contributor with the details (configuration, input file) needed to reproduce the issue.< / h3 >
< ul >
2020-05-30 00:00:07 +02:00
< li > < h3 > exhaleLib: Coding of stereo or multichannel input occasionally leads to slightly in­ creased bit-rates because the predictive joint-channel coding provided by ISO/IEC < a href = "https://www.iso.org/standard/76385.html" > 23003-3< / a > has not been fully implemented. See the functionality roadmap below.< / h3 > < / li >
2020-01-02 02:05:09 +01:00
< li > < h3 > exhaleApp: Only basic WAVE input file reading functionality has been implemen­ ted. Specifically, 8-bit WAVE input is assumed to contain an even number of audio samples, and the Broadcast and Extensible WAVE file formats are not supported.< / h3 > < / li >
< / ul >
< h3 > < br > < b > Roadmap of Upcoming Features< / b > < / h3 >
< h3 > If you are in need of an additional library or application feature < b > not< / b > mentioned below, please contact ecodis or a contributor with a request, and we will see what we can do.< / h3 >
< ul >
2020-01-23 21:00:39 +01:00
< li > < h3 > support for coding with a core coder frame length of 768 samples, no version plan< / h3 > < / li >
2020-06-16 01:00:12 +02:00
< li > < h3 > exhaleLib: completed integration of predictive joint-channel coding, version 1.0.6< / h3 > < / li >
2020-06-21 00:00:00 +02:00
< li > < h3 > exhaleLib: finalization of support for 3.0– 5.1 multichannel coding, no version plan< / h3 > < / li >
2020-05-30 00:00:07 +02:00
< li > < h3 > exhaleLib: speed-ups and further quality tuning for difficult signals, as necessary.< / h3 > < / li >
