Why would you normalize on import ?\r\n\r\nI ended up with the following code to read from the wave file : \r\n```python\r\nimport acoustics\r\nimport wave\r\nfrom scipy.io import wavfile\r\nfile_path = \"whatever.wav\"\r\nwith wave.open(file_path, 'rb') as wav:\r\n    sampwidth = wav.getsampwidth()\r\nfs, data = wavfile.read(file_path) \r\ndata = data / 2**(8*sampwidth-1)\r\nsignal= acoustics.Signal(data, fs=fs)\r\n```\r\n\r\nThis works with `S16_LE`, `S32_LE`, `S24_3LE ` formats (using the ALSA labelling) but would fail with `S24_LE` or `FLOAT_LE ` .\r\nIt would be nice to have any wav red as a float array in the end.\r\n\r\nI would be happy to contribute, I just want to make sure I didn't misunderstand an intentional design choice.","author":{"url":"https://github.com/Nitnelav","@type":"Person","name":"Nitnelav"},"datePublished":"2024-02-07T07:46:36.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/268/python-acoustics/issues/268"}
