Do you load the samples through the interface ?
The audio server wavetable implementation can do that already as it recursively load raw single cycle waveforms from directories so to add any samples you just split the sample into small chunks with some kind of windowing applied to remove crackles, guess it can be done quickly with some software.
Made a quick example : https://vocaroo.com/jG2ppKnGZBh
The sample was exported with this small Python script (which require pydub; pip3 install pydub) :
from pydub import AudioSegment
def triangular_window (i, N):
return 1 - abs(2 * (i - 0.5 * (N - 1)) / N)
audio = AudioSegment.from_wav("female_french_numbers_1_10.wav")
audio_samples = audio.get_array_of_samples()
audio_len = len(audio_samples)
chunk_len = 1348 # 44100 / C1_frequency
chunk_count = round(audio_len / chunk_len)
for i in range(0, chunk_count):
start_index = i * chunk_len
stop_index = start_index + chunk_len
audio_chunk = audio._spawn(audio_samples[start_index:stop_index])
# apply triangular window
chunk_samples = audio_chunk.get_array_of_samples()
chunk_len = len(chunk_samples)
for k in range(0, chunk_len):
chunk_samples[k] = int(chunk_samples[k] * triangular_window(k, chunk_len))
audio_chunk = audio._spawn(chunk_samples)
audio_chunk.export('out/' + str(i).rjust(8, '0') + '.wav', format="wav")Could be used for any samples or even a whole directory with some minor adaptation.
The split may eventually be implemented into the audio server (and so on the interface you could have direct drag & drop) but this is low priority as it can be done already and rather quickly with that script.
This is more an issue for the audio server https://github.com/grz0zrg/fas/ as the client don't play sound on its own anymore.
