Django-Audiofield is a simple app that allows Audio files upload, management and conversion to different audio format (mp3, wav & ogg), which also makes it easy to play audio files into your Django application.

We are using the HTML5 and Flash audio player SoundManager2_

audio_file = AudioField(upload_to='your/upload/dir', blank=True,
                        ext_whitelist=(".mp3", ".wav", ".ogg"),
                        help_text=("Allowed type - .mp3, .wav, .ogg"))

# Add this method to your model
def audio_file_player(self):
    """audio player tag for admin"""
    if self.audio_file:
        file_url = settings.MEDIA_URL + str(self.audio_file)
        player_string = '<audio src="%s" controls>Your browser does not support the audio element.</audio>' % (file_url)
        return player_string

audio_file_player.allow_tags = True
audio_file_player.short_description = ('Audio file player')

Add the following lines in your admin.py::

from your_app.models import your_model_name

# add 'audio_file_player' tag to your admin view
list_display = (..., 'audio_file_player', ...)
actions = ['custom_delete_selected']

def custom_delete_selected(self, request, queryset):
    #custom delete code
    n = queryset.count()
    for i in queryset:
        if i.audio_file:
            if os.path.exists(i.audio_file.path):
                os.remove(i.audio_file.path)
        i.delete()
    self.message_user(request, ("Successfully deleted %d audio files.") % n)
custom_delete_selected.short_description = "Delete selected items"

def get_actions(self, request):
    actions = super(AudioFileAdmin, self).get_actions(request)
    del actions['delete_selected']
    return actions

Then perform following commands to create the table and collect the static files::

./manage.py syncdb

• integrate with django-storage (http://django-storages.readthedocs.org/)

• support more formats
