Hi, sorry if I’m doing something wrong here, I’m very new to all of this.
I’m trying to create an instrumental for a song. I’ve used the Vocal Remover and it’s half worked. There are lots of consonants and hiss-type noises from the singer that remain in the song and I was wondering how I would be able to remove that.
It might be better to look for a karaoke or MIDI version of the song.
and it’s half worked.
Unfortunately, that’s normal. I consider the vocal remover a novelty effect and it’s rarely useful for serious audio work. “You can’t un-fry and egg or un-bake a cake, and you can’t un-mix audio”.
The vocal remover works by subtracting left from right. Everything that’s in the center (identical and in-phase in both channels) will be completely removed. But, there is often some off-center background vocals or off-center or out-of-phase reverb. And, there are usually other lead instruments in the center too.

Are you using an MP3? If so, those might be MP3 compression artifacts and a WAV file ripped from a CD might work better.
I have an audio clip to upload as a sample to see if vocals can be removed better. I’ve tried Vocal Remover and Vocal Reduction and Isolation with limited success. Since I don’t know that much about what the settings really do, maybe somebody could try it and advise what they should be?
I have the .aup files if that can be uploaded. I also have a .wav that should be attached now.
The problem with that track is that the vocal has strong stereo effects that spread the vocal across the stereo field.
Audacity is not able to remove the vocals from that track.
Separating vocals from that track is likely to require long and detailed editing with a program such as “Melodyne” (from $399 at time of writing)
Didn’t want to make my day, did you? 
Not that big of a deal. I’ve been able to clip most sections out and blend (sometimes using Crossfade) the remaining bits together. In most of them, I can’t really tell anything was cut out.
