I thought the sps option will cause us headache. But I tried sps3 on a 60 minutes track; there's no significant delay when seeking through the file on a 3 yrs old computer. Which is good I remember the good old days with mpc slow seeking problem where seeking took a couple of seconds... Nice news. Thanks for testing! From the Readme file: "Some recommendations: - For hard disk based playback you may choose a seek table size as small as about 1/16 of the audio duration without experiencing a significant delay when seeking. Therefore the default size of 5 minutes may be sufficient for a audio duration of up to 80 minutes. - If you manually decrease the frame size (for the LossyWav-preprocessor) you are not advised to choose a value which is less than about 1/4 of the audio duration! " With -sts3 for a 60 minutes file you are a bit outside of the recommendations, because 60 > 48 (3 * 16). That's still ok (unless you are compressing LossyWav-files) but if the audio duration/seektable size- ratio get's considerably bigger seeking will suddenly get very slow! I will possibly increase the minimum seektable size to 10 minutes for the final version. You won't loose much compression efficiency. The following table illustrates this. It shows you how much compression you will loose if compressing 3 minutes of cd audio data with different seek table sizes:-sts# Loss % 3 0.000 5 0.002 10 0.007 15 0.009 30 0.026 60 0.054 Up to 15 minutes it's less than 0.01 percent.I will add support for TAK encoding in the next version. Great! Thank you!Now, for pipe decoding... Thomas
