There's still something off with the Dutch Moose preset. The bass we talked about earlier is steady now but overall there are loud volume spikes. I'm talking about perhaps coming from a very quiet section to a very loud one, it's too slow to bring the volume back down or the other way around.
Hi, is this with the latest one (built in in the latest beta)? I did make some more changes in it. I'll check tomorrow.
One good example is the very beginning of the song Amorphis - Message in the Amber. The song starts heavy and loud and already one second into the song the preset has a very noticeable and abrupt volume change. It goes from loud to soft, too slowly I think, so it's a very annoying effect. I can upload a sample if you want, it would be processed with WatchCat from a .flac file. |

Still the same in beta 013 preset. I loaded (Stereo Tool) in MediaMonkey, then exported it as a settings file and used with WatchCat. The same volume spike still very noticeable and can be seen in Audacity. |

Ah. The deep bass is constant, the spike is mainly in the highs apparently - but also in mid-bass. I don't have a good speaker here now (I'm not in my office) so I'm purely speaking based on looking at the waveform in Audition. Will listen tomorrow morning. -> Ok, re-read your comment and it wasn't about the bass at all . Ok will check this one - it should go down way faster than it does here. -> It's AGC Sudden Jump Protection. If I set the detection values to 5 and 8 instead of 10 and 16, the effect is mostly gone. I still have to test for side-effects (so far it looks good). Edit: There are some side effects, but they actually appear to be good instead of bad. The huge spikes are removed before entering the multibands, so they move down less deep. And the initial spikes are caught by the AGC. So, I'll update this in the preset. The effect isn't completely gone, but that's not really possible without killing all dynamics in dynamic tracks. |

Hi, Hans! Will you add in 9's version?
Hi,- RDS RT end with hex code 0D (Carriage Return) instead of padding with spaces, then stop sending - faster and no unnecessary scrolling. That one is still on my todo list. |

In case you missed it, I posted a thread in the Bug Report forum with an audio track that causes the Delossifier to add "broken speaker" sounding kinds of distortion to it.
I've added a new slider that controls how much correction may be done. If it tries to add too much stuff, I assume that it's bad and turn it off. For the track that you sent me before, this fully fixes the issue. I'm going to run a new build now. The new setting is called "Maximum gap size", default value is 30% (20% seems just sufficient to not affect 96 kbit/s MP3's, at 35% I'm starting to hear things in your test track again).I will add another thing that should completely stop it to try to recover anything in your test track - it's incorrectly detecting it as an MP3, and I will fix that. But both fixes are useful; if you would encode this track as an MP3 then it would still add these weird chirping sounds without today's fix. |

Stereo Tool 9.02 BETA015 1. Not only Stereo Tool, but also the MicroMPX encoder that's now built into this Stereo Tool build is a beta version. One person had hiccups with MicroMPX, which was probably caused by the block size with which we were communicating with the sound card. I've quadrupled it, which appeared to fix the problem, but caused crashes. This build has the original value x2. I will look into the crash later. EDIT: Just fixed a potential issue of that crash (the issue was introduced 2 days ago so it might be it), uploaded MicroMPX version 016.

Why not block size adjustable? For example My Juli@ at 48kHz on MME likes 1920 size. With KS it's perfect at 512 size... etc. Depending on sample rate and soundcards.. it asks different ideal block size. |

Nice, thanks! Seems like it's fixed now in 015. I'll go through some albums to test out more and hopefully can start building my cloud library with WatchCat processed music files!

It's not so much the card that's asking for a different block size, in this specific case where it caused issues it was a Core2Duo with - as the name says - only 2 cores, where apparently the decoding was interfering with the I/O.For example My Juli@ at 48kHz on MME likes 1920 size. With KS it's perfect at 512 size... etc. Depending on sample rate and soundcards.. it asks different ideal block size. If we have to we can do it - but if it's not needed, I'd rather keep it simple.... |

Stereo Tool 9.02 BETA015
Windows 64 Bit Standalone B015 + microMPX B016Attachment: ST902-B015_microMPX-B016.JPG [ 66.33 KiB | Viewed 6044 times ] The top is ST output into a low power test TX, the bottom is me decoding the same signal via MPXTool. At the level where I can no longer decode RDS via RDSSpy from the PIRA using the microMPX output (same card type), can switch across to the MPX output into the same TX and reduce power by another 15-20% before I loose RDS from the MPX derived from ST directly. I realise that some of this stems from the the nature of the codec (per previous post) but thought I'd throw the idea up for review. Cosmetic display bug: The FM Lowpass frequency value is being shown on the main screen for both the FM and Bandpass Lowpass frequency values. Rossco |
