Great, it means that sbc encoder is mostly bug free (at least none of them shows up on this test set with all the available bugfixes applied). Now a good improvement would be to tweak the default 16-bit version of analysis filter to improve its precision. It is a lot faster than the high precision variant and already provides sufficient quality :) -- Best regards, Siarhei Siamashka -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
