spek-alternative's Issues

Building with `wxWidgets-gtk3`?

wxWidgets provides wx-config which is required to build spek-alternative as seen here. But the binary supplied by wxWidgets-gtk3 is named wx-config-gtk3 and trying to build spek-alternative with wxWidgets-gtk3 fails because it isn't looking for the correct file.

How would I build this with wxWidgets-gtk3?

Thanks for reading this. :)

Fails to build against ffmpeg-5.0

This code uses a deprecated ffmpeg API which results in errors when compiling against ffmpeg>=5.0.

Status update?

What is the status of this repo now? I've seen new activity on the original Spek repo. Is this one from fresh upstream? Will these changes be eventually merged there? The releases and README for this GitHub repo hasn't been updated for years, yet I see activity under commits.

Can't build on linux

...with error

error: AM_GNU_GETTEXT_VERSION or AM_GNU_GETTEXT_REQUIRE_VERSION is used, but not AM_GNU_GETTEXT

and several warnings

configure.ac:11: warning: The macro `AC_PROG_LIBTOOL' is obsolete.

Not sure it is actual problem though... I'm on archlinux and it may be troubles with recent changes of wxgtk package.

Fixing Spek for 4k displays

I use 200% zoom when using windows on a 4k display. It would be nice to see the text and the hud be readjusted for such changes.

Homebrew Cask

Thanks for this fork! 🙏

Is there any chance to see this available on Homebrew Cask?

Logarithmic scale for frequency?

I guess it would be nice to have a logarithmic frequency scale toggle; ideally with adittional octaves ticks.

Save spectrum config

can you add a file or something where the spectrum preferences (max dB, min dB, color palette, etc) are saved, to save time instead of configuring it each time you open the program ("feature")

Flatpak

Hello, are there plan to a flatpak build? Please, I need the app and I use Endless OS, I just can install flatpaks from flathub.

Building from git on unix / linux / ubuntu

For Unix you link to:
https://github.com/withmorten/spek-alternative/blob/master/INSTALL.md#bsd-and-gnulinux

That has directions for the original repository, which has not been updated in forever, yours is now for all purposes the goto spek repository.

here are up to date instructions that I used to build from git on my Ubuntu 18.04 system:

sudo apt-get install ffmpeg autopoint intltool libwxgtk3.0-dev libavcodec-dev libavformat-dev
git clone https://github.com/withmorten/spek-alternative
cd spek-alternative
./autogen.sh
make
sudo make install

Command line

Hi,

This is not an issue, just a question. Is it possible to add a command line support?

The main functionality that I'm missing is to be able to save the result in PNG directly through the command line.

Compiling on Windows under MSYS2/MINGW64

Subj.

Has anyone got a working recipe? Ideally one that does not utilize building ffmpeg/avcodec from scratch.

Thanks.

Linux binary?

Hello, thanks for reviving Spek!.. Could you kindly provide a Linux binary? No need for multiple distro-specific binaries, just one static build or an AppImage file. Alternatively make a Flatpak (see #8)

Numerical values?

Is it possible to modify spek so that it produces numerical values in stdout that could be used to calculate the frequency threshold (bandwidth) in various codecs?

metadata/headers are affecting the look of the spectrograms

bug was produced using mac version 0.8.2.3

putting 2 identical mp3s with different metadata into spek produces 2 slightly different looking spectrograms, even when the underlying audio data is identical. (i stripped away the metadata of both files and they had matching md5 hashes. the spectrograms also matched perfectly when their metadata was removed)

File A

original mp3 (metadata mistakenly showed a duration of 74:33:55 when it was really 2:40)

File B

original mp3 -> metadata modified by mpTrim to show the correct duration which is 2:40 (underlying audio data of B is still identical to A)

File C

original mp3 -> metadata cleared with TagStripper
or
original mp3 -> metadata modified by mpTrim -> metadata cleared with TagStripper

the spectrograms i got from spek for A and B were different, yet the filesizes were very similar, so i cleared the metadata of both files using TagStripper. the 2 resulting files with cleared metadata had identical md5 hashes, so basically they were the same file. thus, the underlying audio data of A and B must also have been the same

also curious was that neither A nor B's spectrogram matched up with C's. this feels like a pretty widespread bug that should be easy to duplicate

Porting macOS Spek to Apple Silicon

Apple announced the transition to Apple Silicon (ARM). The transition should be completed in two years from now.
https://developer.apple.com/documentation/apple_silicon

This feature request is about porting Spek to Apple Silikon to make it run natively on newer Macs.
