Re: Trader's Little Helper

Hi there! My apologies if this has already been covered here. I looked for a while (sigh). I'm running "show audio file details" in len mode.
  • I understand how to spot those pesky SBE's
    -b- in the column named "cdr"
  • Just ran across a 24bit flac in a set of 16bit flacs
    cxx in the column named "cdr"

I would like to understand the code for various errors/ problems. I seem recall a list somewhere. It's been a long time, so I might be dreaming.
***************************************

Here's the question -
Is there a list of errors that are possible in TLH?

***************************************
A 2nd question - Here's the latest (so far unknown to me)
  • I found the following in a recent fileset
    3--xx in the column named "problems"

Thanks and keep on keeping on!

Re: Trader's Little Helper

If a wave form is not canonical, does that mean it is lossy or just idiosyncratic? I recorded something from a higher quality radio stream and saved it in wav, and while TLH says there are no problems and shows the format as WAV it also shows that it is not canonical.

If a program (e.g. an audio editor) writes additonal information to the file header that does not correspond to the WAVE file specification, the header is called "non-canonical" (a technical description see here). It does not mean the audio data is lossless/lossy. It just a hint that the file header is non-standard in a way.

The latest TLH release (v2.8.4 build 185) comes with unofficial FLAC v1.3.3 binaries, the previous TLH release (v2.8.3 build 182) comes with the official FLAC 1.3.2 binaries.

To make a long story short: with the v1.3.2 binaries there are no issues when verifying/creating checksum files. I don't know why the v1.3.3 ones don't work - my knowledge of the C programming language is too poor to really understand the FLAC and shntool source code. If someone knows what's going on or can help please PM me.

So, as a workaround just copy the v1.3.2 releases of flac.exe and metaflac.exe (download) to the subfolder CmdlineApps of the TLH installation folder.

Thanks for the info. Saved a lot of searching. Works perfectly
and the thing about Unicode characters
