Modify style of article references in biblatex

Question

The current article style looks like:

But it should look like:

Due to my very limited biblatex skills I'm unfortunately not yet able to customize it as the article should look like.

What do I have to add to the code?

\RequirePackage{filecontents}
\begin{filecontents}{\jobname.bib}
@Article{asmz,
  author  = {Hans Zimmer},
  title   = {Minimal music},
  journal = {Some journal},
  year    = {2013},
  number  = {12},
  pages   = {40-41},
}

\end{filecontents}

\documentclass{article}
\usepackage[style=authortitle,]{biblatex}

\DeclareFieldFormat[article]{title}{\mkbibquote{#1\isdot}}
\renewbibmacro{in:}{}

\addbibresource{\jobname.bib}
\begin{document}
Let's cite! \footcite{asmz}
\printbibliography
\end{document}

Answer 1

Some fiddling with the journal+issuetitle bibmacro alongside with some formatting directives should get things as intended. Notice I had to make some decisions regarding the order of other fields you didn't consider in your example, with repercussions on punctuation. I also use babel to get localized bibstrings such as "Nr.".

\RequirePackage{filecontents}
\begin{filecontents}{\jobname.bib}
@Article{asmz,
  author  = {Hans Zimmer},
  title   = {Minimal music},
  journal = {Some journal},
  year    = {2013},
  number  = {12},
  pages   = {40-41},
}

\end{filecontents}

\documentclass{article}
\usepackage[style=authortitle]{biblatex}
\usepackage[ngerman]{babel}
\usepackage{csquotes}

\renewbibmacro{in:}{}

\renewbibmacro*{journal+issuetitle}{%
  \usebibmacro{journal}%
  \setunit*{\addcomma\space}%
  \printfield{issue}%
  \setunit*{\addspace}%
  \usebibmacro{date}%
  \setunit{\addcomma\space}%
  \iffieldundef{series}
    {}
    {\newunit
     \printfield{series}%
     \setunit{\addspace}}%
  \printfield{volume}%
  \setunit{\addcomma\space}%
  \printfield{number}%
  \setunit{\addcomma\space}%
  \printfield{eid}%
  \setunit{\addcolon\space}%
  \usebibmacro{issue}%
  \newunit}

\DeclareFieldFormat[article,periodical]{date}{\mkbibemph{#1}}
\DeclareFieldFormat[article,periodical]{volume}{\mkbibemph{\bibstring{volume}~#1}}
\DeclareFieldFormat[article,periodical]{number}{\mkbibemph{\bibstring{number}~#1}}
\DeclareFieldFormat[article,periodical]{pages}{\mkbibemph{\mkpageprefix[bookpagination]{#1}}}

\addbibresource{\jobname.bib}
\begin{document}
Let's cite! \footcite{asmz}
\printbibliography
\end{document}
