### Install Python-SoXR with pip

Source: https://python-soxr.readthedocs.io

Use this command to install the Python-SoXR library using pip. If installation fails, upgrade pip and try again.

```bash
pip install soxr

```

--------------------------------

### Install Python-SoXR with Conda

Source: https://python-soxr.readthedocs.io

Install the soxr-python package in a Conda environment. Note that the Conda package name is 'soxr-python', not 'python-soxr'.

```bash
conda install -c conda-forge soxr-python

```

### Basic Resampling with Python-SoXR

Source: https://python-soxr.readthedocs.io

Perform basic audio resampling using the `soxr.resample()` function. The input can be a mono (1D) or multi-channel (2D) numpy array. The function handles conversion to numpy.ndarray with dtype 'float32' if the input is not already a numpy array. The output will have the same dimensions and data type as the input.

```python
import soxr

y = soxr.resample(
    x,          # input array – mono(1D) or multi-channel(2D of [frame, channel])
    48000,      # input samplerate
    16000       # target samplerate
)


```

--------------------------------

### Streaming Resampling with ResampleStream

Source: https://python-soxr.readthedocs.io

Utilize `ResampleStream` for real-time audio processing or handling very long signals. The `resample_chunk` method processes input chunks and returns resampled audio. Set `last=True` when processing the final chunk of input.

```python
import soxr

rs = soxr.ResampleStream(
    44100,              # input samplerate
    16000,              # target samplerate
    1,                  # channel(s)
    dtype='float32'     # data type (default = 'float32')
)

eof = False
while not eof:
    # Get chunk
    ...

    y_chunk = rs.resample_chunk(
        x,              # input aray – mono(1D) or multi-channel(2D of [frame, channel])
        last=eof        # Set True at end of input
    )


```
