Hi
May I ask only 2 questions ?

1) what could i do with all the information provided by the True Peak Scanner component ?
I mean should I use them with some normalization /replay gain or components or foobar features?

2) are there some old version avaible ? I liked the first version

Lossless / Other Codecs / Re: HALAC (High Availability Lossless Audio Compression)
Last post by Case -
The new API is an improvement because it doesn't need a file name, but it seems like full file still needs to be read to memory to fully decode it. It looks like I can start decoding beginning of the track with partially read source file but I don't see a mechanism to ask the library to just decode from partial buffer. Most of the functions crash hard if fed a buffer that doesn't contain a HALAC 0.2.8 file in its entirety.

Edit: since it's your format you of course don't need to worry about being memory-friendly or allow streaming.
PS: the library is still lacking error checking. Simple random altered byte in audio data didn't manage to crash it now (produced audible glitch) but bad header data crashes it hard. Easy to trigger for example by changing the '7' to '8' in version info of 0.2.7 encoded file.

Hi
first i want to thank you for the plugin
do you think could be possibile to add in the Dr Meter context menu ->save results logs to  ?
or maybe in the Dr Meter Results -> save results logs to ?
would so useful and easy .., than change the option in the advanced options
again thanks for the plugin
cheers

Figured out

Icon clipping happens on devices with latest version of stock Google launcher only, as they totally randomly switched from showing banners to round icons. Had to boot a stock Google TV device and wait a few minutes to install updates to see it.
My main test device has no Google services at all so I don't see this.
Android TV emulator isn't doing showing it either, why would it. Seems to have old version of the launcher UI only.

Lossless / Other Codecs / Re: Lossless music stores (files!) not offering FLAC, but other lossless compressed?

Honestly, I didn't intend this topic to be read as "this is a bad thing". Actually I am pleased to see that a free and open format has become dominant. I wonder what could have been if a couple of big players had been more successful - one thing is inferior formats, but then it is the scenario that control over the delivery format could make DRM-infestation much easier. Reminder that we still got a bit of intentional crippling in the market (looking at you, scamQA), we could easily have gotten worse.

Sure there are codecs with a multichannel support that FLAC doesn't offer in its own file format, and when 7.1.4 channel 352/24 in WAVE is a full CD-ROM per minute (isn't that closing in on Netflix' HD video?) there could be some savings up for grabs. Technically not too hard to implement, when there are both codecs and containers around.
But with lossless compression having become close-to-synonymous with FLAC except to the apple crowd who might think that "audio" is synonymous to "mp3 or m4a or wav or aif", I have a hunch that a vendor who tried to deliver high-channel files as WavPack would probably regret it after a few days of overworked customer support - even when a self-extracting format was available, just click it then! (Yes SFX was discontinued with WavPack 5, I don't know if anyone has really come to miss it.)

I think that part of it is that FLAC as an open standard is natively decoded by some chipsets, in ways that WavPack isn't.  Only in the past 10 years or so have internet speeds been consistently fast enough for lossless audio to be feasible for the mainstream, and even then only a small percentage of the mainstream that really care or know about it.  Multichannel is an even smaller slice, when you taken into account those that have the equipment to make use of the capability.  It took time for FLAC to become the lossless standard from SHN, due to the obvious benefits; maybe it's just a bit down the road before the same can be said for multitrack audio.

Lossless / Other Codecs / Re: FrAD: Fourier Analogue-in-Digital (Analogue Audio Archive Codec)
Last post by ktf -
I fail to see what is analog about this.

So instead of sampling in the time domain (as PCM does) sampling happens in the frequency domain. But those frequencies are still represented by numbers which makes it digital. There is nothing analog about it. Sampling in the time domain also 'preserves analog waveforms' just fine.

The FAQ has an interesting take on what is lossless:
Quote
The loss in 12 and 16 bits can be taken as a significant loss of quality that anyone can hear [...] and that the loss is not actually a serious quality loss as you might fear. [...] Anything above 24-bit is beyond the dynamic range that the human ear can perceive, 0-80 dB SPL, so it's hard for human ears to notice the difference. So even though the PCM itself may not be preserved intact, the human ear will still have the exact same auditory experience, and we can say that it meets the definition of ‘lossless’.
By that definition, many codecs usually regarded as lossy are suddenly lossless too.
Quote
While complete lossless is virtually impossible outside of using PCM as it is, FrAD guarantees that at bit depths of 24 bits and above, the sound quality is indistinguishable from the original PCM to human and animal hearing.
So, seriously, what is the point of this?
