Sounds & Fonts

[Cubbarooney104]

It seems to me that the only sounds that can be used are the ones that come with the app. Is this true? Or is there something I'm overlooking? Same thing with fonts, can new ones be added?

Just wondering,
Thanks,
Cubbarooney

One way to get a list of fonts might be to pull a long list of font names off somewhere and see which ones don't produce errors if you try to use them.

Something like:

# coding: utf-8
from PIL import ImageFont

fonts = ["Helvetica", "Courier", "FontNameThatDoesNotExist", "Arial", "PoopingPenguins", "Inconsolata"]

installed_fonts = []
for font in fonts:
    try:
        ImageFont.truetype(font, 10)
        installed_fonts.append(font)
    except:
        print "Font '"+font+"' not found."


print "\nThe installed fonts are:\n" + "\n".join(installed_fonts)

That won't work (console.set_font never throws an exception, it just ignores invalid fonts).

[Webmaster4o]

Ah, thanks. What about PIL.ImageFont?

[omz]

I think that would work, yes.

[Webmaster4o]

Edited, but still haven't tested. Can someone test that code for me?

[ccc]

Yes. The code works as expected if you remove the quotes around "font" in the append() line.

Of course it is also best practice to change except: to except TypeError:. ;-)

[Webmaster4o]

Right, @ccc, but I didn't know what kind of exception it would throw since I'm not somewhere I can test it.

@administrators @Omz,

I love that you can play sounds directly from their urls. Is there a way to simplify the script for this?

[cvp]

@jerovargas something like this?

import ui 
webview = ui.WebView()
webview.frame = (0,0,600,100)
url = 'https://s3-us-west-2.amazonaws.com/s.cdpn.io/123941/Yodel_Sound_Effect.mp3'
webview.load_url(url)
webview.present('sheet') 

[ccc]

What about using these apis... http://omz-software.com/pythonista/docs/ios/sound.html

[cvp]

@ccc He asked to play directly from url...

@jerovargas, here’s a more light-weight alternative, which does play the sound ”directly from the url”, but only after it has been fully downloaded. I tried to combine streaming with play_effect, but was unsuccessful.

import tempfile
import sound
import requests

def play(url):
    with tempfile.NamedTemporaryFile(suffix='.caf') as fp:
        r = requests.get(url)
        r.raise_for_status()
        fp.write(r.content)
        sound.play_effect(fp.name)
        
play('https://s3-us-west-2.amazonaws.com/s.cdpn.io/123941/Yodel_Sound_Effect.mp3')

@jerovargas, ok, a version that streams a longer file instead of downloading it first.

import objc_util

objc_util.load_framework('AVFoundation')
AVPlayer = objc_util.ObjCClass('AVPlayer')

def play(url):
    audio_player = AVPlayer.playerWithURL_(objc_util.nsurl(url))
    audio_player.play()
    return audio_player

player = play('https://file-examples.com/wp-content/uploads/2017/11/file_example_MP3_2MG.mp3')

input('Press enter to stop')

player.pause()
