The md.audio doesn't work with a local file

[MrOneTwo]

I'm loading a sound file, that the notebook generates, like so:

SAMPLES_FILE = "samples.bin"

data_unpacked = np.asarray(
    [d[0] for d in struct.iter_unpack("<H", Path(SAMPLES_FILE).read_bytes())]
)

# The microphone that recorded the samples has a certain bit depth for each sample.
# Convert to signed 16bit samples.
_data_float = data_unpacked / 8192.0
soundwave = _data_float * np.iinfo(np.int16).max

SAMPLE_RATE = 32000
BYTES_PER_SAMPLE = 2

with wave.open(str(Path(SAMPLES_FILE).with_suffix(".wav")), "w") as f:
    f.setnchannels(1)
    f.setsampwidth(BYTES_PER_SAMPLE)
    f.setframerate(SAMPLE_RATE)
    f.writeframes(data_unpacked.astype(np.int16))

mo.vstack(
    [
        mo.md("Example sound file:"),
        mo.audio(src="samples.wav"),
    ]
)

#with open(str(Path(SAMPLES_FILE).with_suffix(".wav")), "rb") as _p:
#    mo.audio(src=_p)

The notebook can access the samples.bin, but it fails to embed an audio player with samples.wav. If I change to the App view I see, in the inspect panel, that samples.wav has 404'ed. Is it that Marimo's serve doesn't serve that file?

I have also tried the second approach, using file context. Also, doesn't work. It doesn't even show the audio player with that code, so I might be doing something wrong there.

This sounds like a bug - I will create an issue and fix it this week.

[MrOneTwo]

any update on this?

[MrOneTwo]

oh, I found the issue on the Issues tab, with a workaround.

This is now fixed, on version 0.3.7.

[akshayka]

This is now fixed. Here is a recipe.

with open("audiofile.wav", "rb") as _f:
    audio_player = mo.audio(src=_f)
audio_player
