python-soxr's Issues

Compiler crash in AnalyseDeclarationsTransform

Hello,

I am trying to build it from source and I am getting an error :

$ python3 setup.py bdist_wheel --verbose

Do you have any pointers to resolve it ?

Issue related to INTERLEAVE2

Hi Team,

I was working on librosa for arm64 but while testing with pytest, the testcase ‘tests/test_core.py’ is failing due to below error:
E ImportError: /root/miniconda3/envs/testenv/lib/python3.9/site-packages/soxr/cysoxr.cpython-39-aarch64-linux-gnu.so: undefined symbol: INTERLEAVE2 /root/miniconda3/envs/testenv/lib/python3.9/site-packages/soxr/__init__.py:9: ImportError

Here are the detailed log: GHA_arm64

This seems related to python-soxr. I made sure to install soxr from pypi, and validated that it is installing required library cysoxr.cpython-38-x86_64-linux-gnu.so too.
But seems this .so file is having some reference related to INTERLEAVE2, which requires your opinion and suggestion to make it working for arm64.

any ideas?

conda-forge packaging

👋 @dofuuz are you at all interested in providing a conda-forge package for this library?

libsoxr itself is already available https://anaconda.org/conda-forge/soxr so there shouldn't be any significant barrier here.

The main benefit of conda-forge packaging this library would be ease of installation and management for downstream projects (eg librosa).

"always_inline" error when building on 32bit

I packaged python-soxr for Slackware 15.0. I am stuck to v0.2.4 due to the system not having a newer cython.

64bit builds work without issue, however, I was notified the build fails on 32bit systems while trying to build the internal libsoxr. After spinning up a 32bit VM, I confirmed it is unable to compile libsoxr/src/cr32s.c with the following error:

error: command '/usr/bin/gcc' failed with exit code 1

Oddly enough, if I compile libsoxr by itself using cmake, I run into no such problems. However, since I'm stuck running 0.2.4, I am unable to tell python-soxr to use the system libraries for libsoxr.

I know this is not standard usage for python and I'm requesting this on an older version, but building packages this way is the only way the software repo supports, and all dependencies have to be available to submit other packages (this is a dependency for another package I maintain).

Any hints or suggestions I could do to enable compiling on 32bit while we wait for a version bump of cython from the main distro? I appreciate any help you might be able to provide.

soxr-python can't be found in conda-forge

I'm trying to install librosa 0.10 through conda (actually micromamba, but that shouldn't matter) but I receive the following error:

error    libmamba Could not solve for environment specs
    The following package could not be installed
    └─ librosa 0.10**  is uninstallable because it requires
       └─ soxr-python >=0.3.2 , which does not exist (perhaps a missing channel).

I am using conda-forge as a channel for packages. I tried adding the default one but nothing changed. This is unexpected because https://anaconda.org/conda-forge/soxr-python says that soxr-python 0.3.3 should be available on conda-forge.

I'm on a Mac M1, MacOS 13.3.1.

resample_chunk and resample methods return very different results

It seems that resample_chunk from the ResampleStream class returns very different results than just using soxr.resample. Is this the expected result?

Expect a successful installation of Python-Soxr without encountering the AttributeError related to the 'version' attribute.

Environment Information

Operating System: Linux debian risc-v
Python Version: 3.11
Python-Soxr Version: (latest commit or release version)

Any Solution?

Bug in dithering

In system that 'unsigned long' is 32-bit(i.e. Windows, 32-bit Linux), dithering is not working as expected.

In those systems, dithering has pattern of every 16 samples. Later 8 samples are always ±0.

Random variable used in dithering is unsigned long.
And it should have 56+ bits. 32-bit is not sufficient and it cause fixed 0 output.

I reported this issue to upstream:
https://sourceforge.net/p/soxr/discussion/general/thread/5d68180432/
but, it's not likely to be fixed. Maintainer is not active for 3+ years.

I'll wait for response about a month. After than, I'm going to fix this issue in my fork of libsoxr.

Python-SoXR now supports x86 and ARM processors.
(ppc64le is also supported but it's not being intensively tested.)

In other platforms, an error like below can occur during pip installation or building.

In this case, see BUILDING.md and build Python-SoXR using system libsoxr.

Release GIL while resampling

Hi, it's nice to see there's a convenient library to use soxr in python.
But it seems that it will not release GIL while resampling.
Can it release GIL while resampling?

No *-manylinux_i686 wheel

Adding -msse to compiler option will fix this issue.
But I'm looking for more elegant way to solve it. (Detecting compiler option automatically)

No pp*-macosx_x86_64 wheel

Numpy bug numpy/numpy#15947

No PyPy pp*-win32 wheel

https://github.com/dofuuz/python-soxr/runs/2596317718

setuptools_scm does not generate correct version name. I do not know why.

I'll fix these issue if there are reasonable request and spare time.

Feel free to open issue or PR.

No SIMD64 support (relatively slow VHQ mode)

It's not easy to solve because not every system supports AVX.
This needs different compiler flags for each source files and systems.

So again, I'm looking for more elegant way to solve it. (Detecting compiler option automatically)

Using external libsoxr may solve this problem. Build with --use-system-libsoxr flag if you really need faster VHQ mode.

Non-deterministic output issue

When using int16 output, soxr uses dithering and it's random.
Each run of soxr will produce different results.

Related issue:
chirlu/soxr#8

I'm considering to fix random seed of soxr to make result deterministic.

If anyone has opinion about this, feel free to leave comment!
