Details:

>> audiowrite("IRmerge.wav",y,fs,'BitsPerSample',24);

>> audioinfo("IRmerge.wav")

ans =

  scalar structure containing the fields:

    Filename = C:\Users\DamageG\Dropbox\damnet\Octave\IRmerge.wav
    CompressionMethod =
    NumChannels =  1
    SampleRate =  96000
    TotalSamples =  48000
    Duration =  0.50000
    BitsPerSample =  32
    BitRate = -1

Also note the behavior for 32 bit samples

>> audiowrite("IRmerge.wav",y,fs,'BitsPerSample',32);
>> audioinfo("IRmerge.wav")
ans =

  scalar structure containing the fields:

    Filename = C:\Users\DamageG\Dropbox\damnet\Octave\IRmerge.wav
    CompressionMethod =
    NumChannels =  1
    SampleRate =  96000
    TotalSamples =  48000
    Duration =  0.50000
    BitsPerSample = -1
    BitRate = -1
